Wie man unter Debian „E: Broken packages“ am einfachsten löst

Release-Upgrades von Debian GNU/Linux-Kisten sind immer so eine Sache. Bei der Migration von Stretch auf Bullseye stand ich vor folgendem Problem:

# apt-get dist-upgrade
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Calculating upgrade... Done
The following packages have been kept back:
  apt apt-utils cpp gcc libmariadb-dev
0 upgraded, 0 newly installed, 0 to remove and 5 not upgraded.
# apt upgrade apt
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Calculating upgrade... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 apt : Depends: libapt-pkg6.0 (>= 2.2.4) but it is not going to be installed
       Depends: libstdc++6 (>= 9) but 8.3.0-6 is to be installed
 apt-utils : Depends: apt (= 1.8.2.3) but 2.2.4 is to be installed
E: Broken packages

Wie ich endlich, nach all den Jahren herausgefunden habe, löst man solche Probleme am einfachsten mit dem Downgrade eines oder mehrerer Pakete. Dies, indem man apt-get install %paketname%=%versionsnummer% ausführt.

Welches Paket man im obigen Fall downgraden muss? Gar nicht so einfach. Irgendeinmal hatte ich es dann doch herausgefunden:

# apt-get install gcc-10-base=10.2.1-6

Danach flutschte apt-get upgrade durch.

Von Stretch nach Bullseye mit gravierenden Problemen

Gestern lüpfte ich einen zweiten OpenVPN-Server von Debian Stretch auf Bullseye.

Das erfolgte leider nicht kurz- und schmerzlos. Ich kämpfte mit und debuggte während 16 Stunden (abzüglich 7 Stunden Schlaf) an folgenden Problemen:

Konsolen-, SSH- und Telnet-Logins dauern 1min30sec

D.h. nach Eingabe des Passwortes scheint das System zu hängen. Wer sich in Geduld übt, landet nach eineinhalb Minuten in der gewohnten Shell.

Bei mir bildeten sich in diesen ersten 90 Sekunden bereits viele Schweissperlen, denn wie flickt man ein Debian GNU/Linux, wenn man sich nicht mehr einloggen kann? Mittels grub in den Single User/Recovery Mode zu booten wäre ein noch grösserer Alptraum geworden …

Meldungen in syslog:

...
Sep 18 22:40:43 OPENVPN2 systemd[1]: Starting User Manager for UID 1000...
Sep 18 22:42:13 OPENVPN2 systemd[1]: user@1000.service: Main process exited, code=exited, status=1/FAILURE

Sep 18 22:42:13 OPENVPN17 systemd[1]: Failed to start User Manager for UID 1000.
...

Die Lösung:

# apt-get remove gpgconf
...
The following packages will be REMOVED:
  dirmngr duplicity gnupg gnupg-agent gnupg2 gpg gpg-agent gpg-wks-client gpg-wks-server gpgconf gpgsm libgmime-2.6-0 libgpgme11
  libnotmuch4 mutt python3-gpg samba-dsdb-modules scdaemon

Die vielen zu deinstallierenden Pakete liessen mich kurz zweifeln, aber das System lief nach deren Deinstallation problemlos weiter.

Wobei, wenn ich die Kommentare so lese: Eventuell war gpgconf gar nicht das Problem, sondern der Nameserver, der nicht reagierte (siehe unten).

Netzwerkprobleme

Probleme mit named und localhost

BIND 9 ist zwar an localhost (127.0.0.1) gebunden und lauscht auf dem Interface …

# lsof -i :53
COMMAND PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
named   653 bind   23u  IPv4  15673      0t0  UDP localhost:domain 
named   653 bind   24u  IPv4  15679      0t0  UDP localhost:domain 
named   653 bind   25u  IPv4  15680      0t0  TCP localhost:domain (LISTEN)
named   653 bind   27u  IPv4  15681      0t0  TCP localhost:domain (LISTEN)
named   653 bind   29u  IPv4  15682      0t0  UDP 10.1.2.3:domain 
named   653 bind   30u  IPv4  15683      0t0  UDP 10.1.2.3:domain 
named   653 bind   31u  IPv4  15684      0t0  TCP 10.1.2.3:domain (LISTEN)
named   653 bind   32u  IPv4  15685      0t0  TCP 10.1.2.3:domain (LISTEN)

… aber die Namensauflösung funktioniert nicht. Wenn man mit telnet 127.0.0.1 53 eine Session aufbauen will, hängt die Verbindung.

Mittels strace analysierte ich dann was im Hintergrund genau vor sich ging, und verglich die Ausgabe mit einem strace auf einem Server, bei dem die Namensauflösung funktionierte:

Defekter Server:

# strace ping -c 1 emeidi.com

close(5)                                = 0
...

Funktionierender Server:

# strace ping -c 1 emeidi.com
...
socket(AF_INET, SOCK_DGRAM|SOCK_CLOEXEC|SOCK_NONBLOCK, IPPROTO_IP) = 5
setsockopt(5, SOL_IP, IP_RECVERR, [1], 4) = 0

recvfrom(5, "UK\201\200\0\1\0\1\0\r\0\r\6emeidi\3com\0\0\1\0\1\300\f\0\1"..., 2048, 0, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("127.0.0.1")}, [28->16]) = 463

sendto(5, "W}\1\0\0\1\0\0\0\0\0\0\6emeidi\3com\0\0\34\0\1", 28, MSG_NOSIGNAL, NULL, 0) = 28

close(5)                                = 0
...

Macht man dasselbe mit der internen IP des Servers (bspw. 10.1.2.3) kann eine Session aufgebaut werden. Die Namensauflösung konnte ich nicht durchführen, weil mir der oder die Befehle nicht geläufig waren — im Nachhinein aber las ich dann, dass es sich bei DNS-Abfragen nicht um Klartextkommandos handelt.

Nun gut, dies bewog mich zu einem Workaround, ohne das eigentliche Problem zu beseitigen. Ich passte kurzerhand meine /etc/resolv.conf an:

#nameserver 127.0.0.1
nameserver 10.1.2.3

options timeout:1
options single-request

Ich vermutete zuerst Probleme in systemd-resolved. Installieren resp. entfernen tut man das Paket mit:

# apt-get install libnss-resolve
# apt-get remove libnss-resolve

Ist das Paket installiert, hat man neben /etc/resolv.conf auch noch Konfigurationen in /etc/systemd/resolved.conf und /run/systemd/resolve/resolve.conf. Typischer systemd-Wahnsinn. (siehe dazu Ubuntu – 18.04 Unable to connect to server due to “Temporary failure in name resolution” sowie Ubuntu 18.04 DNS resolution fails after a while)

Als ich systemd-resolved mit meinen Pröbelein zerschossen hatte, tauchten in /var/log/syslog noch folgende Fehlermeldungen auf:

Sep 18 20:35:04 localhost dbus-daemon[329]: [system] Activating via systemd: service name='org.freedesktop.resolve1' unit='dbus-org.freedesktop.resolve1.service' requested by ':1.15' (uid=0 pid=2015 comm="resolvectl ")
Sep 18 20:35:04 localhost dbus-daemon[329]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.resolve1.service': Unit dbus-org.freedesktop.resolve1.service not found.

Siehe auch Activation via systemd failed for unit ‚dbus-org.freedesktop.resolve1.service‘: Unit dbus-org.freedesktop.resolve1.service not found

Site-to-site OpenVPN erlaubt Pings in nur eine Richtung

Die Sache wurde immer mysteriöser: Aus dem entfernten Subnetz, in welchem der hier Probleme verursachende Server steht, konnte ich problemlos zur anderen Site pingen. Sowohl den VPN-Endpunkt, als auch alle anderen IPs im Subnetz hier. Das funktionierte auch von anderen Geräten im entfernten Subnetz aus.

Doch im Umkehrschluss funktionierte das nicht; d.h. von meinem Heimnetzwerk konnte ich nur den OpenVPN-Endpunkt pingen, aber nichts im entfernten Subnetz. Die ICMP-Pakete kamen zwar beim Zielgerät an (bspw. dem Internet-Router), dieser antwortete, aber das Antwortpaket wurde dann von auf dem entfernten OpenVPN-Endpunkt nicht von eth0 auf tun0 weitergeleitet.

Immerhin lernte ich für das Debugging nützliche tcpdump-Befehle kennen:

# tcpdump -n icmp and host 10.1.2.1
# tcpdump -i tun0 -n icmp and host 10.1.2.1
# tcpdump -i eth0 -n icmp and host 10.1.2.1

Die Ausgabe ist auch deshalb hilfreich, weil derselbe ping-Prozess immer dieselbe id trägt. Und die Sequenznummern sieht man auch gleich angezeigt. So konnte man isolieren, wo genau die ICMP-Pakete „verloren“ gingen respektive noch durchkamen.

Ausserdem kann man iptables so konfigurieren, dass sie verarbeitete Pakete ins syslog loggen (eine Regel iptables -I FORWARD -i eth0 -o tun0 -j ACCEPT existiert dabei schon und ist aktiv):

# iptables -I FORWARD -i eth0 -o tun0 -j LOG --log-prefix "OUTGOING "
# iptables -I FORWARD -i tun0 -o eth0 -j LOG --log-prefix "INCOMING "

Das Logging wird deaktiviert, indem man die Regel wieder entfernt:

# iptables -D FORWARD -i eth0 -o tun0 -j LOG --log-prefix "OUTGOING "
# iptables -D FORWARD -i tun17 -o eth0 -j LOG --log-prefix "INCOMING "

In dmesg entdeckte ich dann auch noch folgende Fehlermeldungen, was mich bewog, den Kernel zu aktualisieren:

...
cgroup2: unknown option "nsdelegate,memory_recursiveprot"
...

Die finale Lösung: Aktualisiere von Kernel-Version 4.9.0-16 auf 5.10.46-4, und Neustart.

# apt-get install linux-image-amd64

Kein Witz: Tigris holt Ex-Geliebte von Alain „Tigrillo“ Berset ab

Halt! Gemäss Ringier-Sprech darf es natürlich nicht „Ex-Geliebte“ heissen, sondern „Bekannte“:

Eine Bekannte des Innenministers Alain Berset (49) ist rechtskräftig verurteilt worden, weil sie erfolglos versucht hatte, 100’000 Franken vom SP-Bundesrat zu erpressen.

Quelle: Bundesanwaltschaft will Sonderermittler einsetzen

Zurück zum Thema: Alain Berset verwendet(e?) gemäss Weltwoche-Artikel den Email-Alias alaintigrillo für seine Schürzenjagden. Tigrillo ist ein anderer Name für das zentralamerikanische Tier Oncilla (Leopardus tigrinus).

Und jetzt der Hammer: Die Ex-Geliebte Bekannte wurde nach dem Erpressungsversuch von der Einsatzgruppe Tigris abgeholt. Denn:

Die Einsatzgruppe wird beigezogen, wenn im Einzelfall mit einem erhöhten Risiko von Gewaltanwendung gerechnet werden muss.

Mein Fazit: Irgendwie enthält die Story einfach zu viele Tiger, als dass es reiner Zufall sein könnte. Das ist alles ein abgekartetes Spiel. Ergo: #tiggergate

Allerlei Wissenswertes über Geschirrspüler

  • You do not need to pre-rinse
  • The most powerful jets in a dishwasher shoot upwards from the bottom, so stack the dirtiest items on the lower shelf and the cleaner or more fragile items above. This is also why your bowls, containers and cutlery should face down.
  • A full dishwasher dries better than a half-full dishwasher
  • A full dishwasher can clean 144 items with roughly 13 litres of water, or anything between eight and 20. According to a study by the University of Bonn, hand washing the same load uses, on average, 100 litres of water.

Tweets, die man lieber nicht abgeschickt hätte. Heute: Reto Lipp, SRF

Ich glaube wir sind in der Diskussion auf dem richtigen Weg, wenn wir aus der Risikomanagement-Lehre den Impact (die Auswirkungen, die Schwere eines Ereignisses; hier: Tod) und die Probability (Eintretenswahrscheinlichkeit über einen bestimmten Zeitraum) zweier Optionen miteinander vergleichen.

Doch ich verstehe nicht ganz, wer für den Stuss hier verantwortlich ist — Niall Ferguson, ein etwas erfolgreicherer Historiker als ich, der inkoherent etwas zusammenlabert, oder Reto Lipp, der unvollständig oder falsch zitiert/übersetzt.

Liest man diesen Tweet wortwörtlich, hat jemand eine Chance von 10 Prozent, an Covid-19 zu erkranken. Für wen gilt diese Zahl? Mann, Frau, Alter, Standort, sozialer Status, andere Erkrankungen usw. usf. Über welchen Zeitraum hinweg? Ehrlich gesagt gehe ich nach derzeitigem Wissensstand davon aus, dass jeder Mensch auf diesem Planeten (mindestens) einmal von SARS-CoV-2 infiziert werden wird.

Will Ferguson sagen, dass zehn Prozent aller Infizierten dann tatsächlich auch Erkranken? Und: Erkrankung ist für mich zu undifferenziert: Asymptomatisch (die in der Pandemie erfundenen „Gesunden Ungesunden“)? Ein leichter Husten? Hospitalisierung? Intensivstation? Long Covid? Man weiss es nicht.

Spätestens aber der Vergleich mit der Impfung macht absolut keinen Sinn mehr, wenn man Lipps Tweet wortwörtlich nimmt: Habe ich eine Chance von 1 zu 10’000, geimpft zu werden? Bei einer Impfquote von schweizweit über 50 Prozent? Ob man geimpft wird oder nicht ist kein statistisch verteiltes Ereignis, sondern hängt direkt mit der Willensbekundung einer Person ab. Entweder organisiert man sich einen Termin und lässt sich impfen, oder aber man entscheidet sich dagegen.

Ich versuche jetzt zu erraten, was Lipp (oder: Ferguson?) eigentlich sagen wollte:

Über den Zeitraum des Ausbruchs der SARS-CoV-2 „Pandemie“ bis heute betrachtet, stirbt einer von zehn Infizierten (10 Prozent). Einer von zehntausend (0.01 Prozent) stirbt an der Impfung. Für welches Tor entscheidet ihr euch?

Obwohl nun sauber ausgelegt macht alles weiterhin keinen Sinn, denn: Ich weiss nicht, von wo diese Zahlen stammen sollen, aber sie erscheinen mir beide kreuzfalsch. Keine Gesundheitsbehörde der Welt würde bei einer solchen „Pandemie“ eine Impfung zulassen (auch nicht unter Notzulassung), welche einen von zehntausend Impflingen tötet (bei der Beulenpest, die 30 Prozent der Bevölkerung umbringt, sähe es wohl anders aus). Genau so wenig sterben 10 Prozent an einer SARS-CoV-2-Infektion. Die Infection Fatality Rate bewegte sich in einer im März 2021 publizierten Auswertung der WHO global bei 0.15 Prozent (Quelle). Ich glaube nicht, dass sich an dieser Zahl seither massivstens etwas geändert hat.

Nachtrag: In die Impfvariante nicht miteinberechnet wurde zudem, dass auch geimpfte Leute sich weiter infizieren können, erkranken können und einige davon (wie viele?) an Covid-19 sterben werden.

Fazit: Liegt der Fehler bei Ferguson, sollte er sich überlegen, sich bei der quantitativen Geschichtsschreibung von einem Zahlenprofi unterstützen zu lassen. Falls Lipp der Fehler unterlaufen ist, sollte er den Tweet löschen und dann noch einmal sauber und korrekt aufschreiben.

Notfallmässig eine Reverse Shell auf einem Linux-System aufbauen

Heute habe ich auf einem meiner Linux-Systems nach langer Zeit wieder einmal apt-get upgrade durchgeführt. Eines der wenigen System in meinem Fuhrpark, auf welchem noch Debian Stretch läuft.

Per SSH aus der Ferne eingeloggt, winkte ich die Meldungen durch — und musste offenbar übersehen haben, dass apt-get vor hatte, eine ganze Ladung kritischer Dienste zu entfernen. Unter anderem auch das Paket openssh-server. Nachdem das Update durch war, logge ich mich mittels Druck auf Ctrl-D aus. Und sah erst dann monits Warnmeldungen in meiner INBOX, dass auf TCP 22 kein SSH Daemon mehr lauschte. Doch dann war es bereits zu spät — ich hatte die letzte „Brücke“ zum Server soeben mit Ctrl-D in die Wüste geschickt.

Alle meine Systeme sysloggen via Site-to-Site-VPN auf einen zentralen ELK-Server. In Kibana dann die Hiobs-Botschaft:

sshd[10954]: error: rexec of /usr/sbin/sshd failed: No such file or directory

Sowie

sshd[10954]: fatal: chroot("/run/sshd"): No such file or directory [preauth]

Da der Server 13 Kilometer weit weg in der Wohnung eines Bekannten steht, hatte ich den Salat. Ich wollte eine Autofahrt vor Ort unbedingt vermeiden.

Glücklicherweise war der Bekannte gerade zu Hause und erklärte sich bereit, mir in diesem Notfall als manuelles, menschliches KVM zu helfen.

Als erstes leitete ich ihn via iMessage an, sich in den Laptop einzuloggen. Das klappte. Anschliessend wollte ich ihn zwei Befehle ausführen lassen:

$ sudo su -
# apt-get install openssh-server

Doch bereits der erste Befehl produzierte eine Fehlermeldung:

-bash: sudo: command not found

Himmelheiland, war sogar sudo deinstalliert worden?!

Immerhin su funktionierte, aber ich wollte dem Helfer nicht zumuten, das 32-stellige, zufällig generierte Passwort mühsam von iMessage auf die Laptop-Tastatur abzutippen.

Ich wollte schon aufgeben, da kam mir eine Blitzidee: Ich benötigte eine Reverse Shell unter dem nicht-privilegierten Benutzer, und dann könnte ich selber das Problem autonom lösen.

Das VPN war wegen eines Neustarts zusammengebrochen (genau dieser Server ist der entfernte Endpunkt), aber glücklicherweise hatte ich ein zweites System im entfernten Netzwerk, auf welchem ein SSH-Server mit einer öffentlichen IP lauscht. Ich war also zusätzlich parallel auf diesem zweiten Server eingeloggt. Zu diesem benachbarten Server sollte das Reverse Shell aufgebaut werden.

Eine Google-Suche lieferte folgende wichtigen Seiten zu Tage: Bind Shells and Reverse Shells with netcat, Hacking with Netcat part 2: Bind and reverse shells, Complete guide to Reverse Shells sowie Su: must be run from a terminal.

Der Bekannte gab nun auf dem zerschossenen Linux folgenden Befehl ein:

$ nc -lvp 12345 -e /bin/bash

Auf dem Schwester-Server gab ich dann ein:

$ nc -nv 10.1.2.3 12345

Wobei 10.1.2.3 die IP des zerschossenen Systems war.

Die Verbindung war zustande gekommen, aber ich sah keine richtige Shell. Befehle konnte ich eingeben (bspw. ls -l), und das Resultat wurde auf meinem Bildschirm angezeigt.

Problem: Als ich su ausführen wollte, wurde das mit der Fehlermeldung su : must be run from a terminal verhindert.

Zuerst überlegte ich mir den Weg über Scripts: How to pass the password to su/sudo/ssh without overriding the TTY? und su pass password to script.

Doch nach Konsultation von Getting around „su : must be run from a terminal“ schaffte ich eine wirklich vollständig brauchbare Shell nach Eingabe des folgenden Befehls:

python -c 'import pty; pty.spawn("/bin/bash")'

Einschub: Unter Stretch funktioniert das, unter Bullseye sollte man nun folgenden Befehle verwenden:

python3 -c 'import pty; pty.spawn("/bin/bash")'

Hurra, ich hatte eine Shell! Aber Achtung: Ein fahrlässiges, aus Gewohnheit gedrücktes Ctrl-C killt die netcat-Verbindung, nicht das laufende Programm.

Andere Varianten unter Zuhilfenahme anderer potentieller Bordmittel wie Perl, PHP etc. sind in Spawning a TTY Shell dokumentiert.

Nun also wollte ich su anwenden, realisierte erst dann aber, dass das in meiner Passwort-Datenbank hinterlegte 32 Zeichen lange Passwort nicht korrekt war. Ich hatte bei der Installation vergessen, dass viel zu einfache dummy-Passwort anzupassen … Als ich dieses eingegeben hatte, landete ich in einer root-Shell.

Doch oha: openssh-server liess sich wegen Abhängigkeitsproblemen nicht installieren.

Was nun? Ich musste irgendwie einen persistenten Server als ersten Brückenkopf einrichten, der beim versehentlichen Betätigen von Ctrl-C auf meiner Seite weiter lief und erneute Verbindungsversuche zuliess.

Ich überlegte mir, ein PHP-Backdoor-Script zu installieren (php-reverse-shell, Quellcode), doch wie konnte ich dieses so einrichten, dass es permanent oder periodisch automatisch Verbindungsversuche unternehmen würde?

Nach etwas tüfteln dann die viel einfachere Lösung:

# apt-get install telnetd

Besser wäre eigentlich gewesen:

# apt-get install telnetd-ssl

Via: How do I turn on telnet service on for a Linux / FreeBSD system?

Und nun hatte ich wieder einen „sauberen“ Zugang zum Server.

Die nachfolgenden Stunden verbrachte ich damit, den Server von Stretch auf Buster und dann auf Bullseye zu lüpfen und eine Ladung Pakete zu installieren, welche apt heimtückisch entfernt hatte: OpenSSH, sudo, cron, OpenVPN, Samba, monit.

Raspberry Pi meldet „Workqueue: events_freezable mmc_rescan“ (Virtual Memory/Swap-Problem)

Seit einiger Zeit ging mein Raspberry Pi 3 zwischen 4 und 5 Uhr morgens „offline“. Meine monit-Installationen meldeten mir dann jeweils, dass der SSH-Server auf dem RPi nicht mehr zu erreichen war (gestern bspw. traf die Meldung um 4:24 Uhr ein).

/var/log/syslog enthielt nachfolgende Meldungen. Die Nennung von mmc_get_card liess mich aufhorchen, weshalb ich eine neue Micro SD-Karte bestellte und die alte Karte auf die neue klonte. Leider liess sich damit das Problem nicht beheben.

Die Lösung fand ich via Pi freezing up 4 times a day – Workqueue: events_freezable mmc_rescan #1522 und via SWAP on Raspberry Pi / SD = AUTOCRASH und via Workqueue: events_freezable mmc_rescan crash with Raspbian kernel 4.14.79-v7+ hier: Linux Kernel panic issue: How to fix hung_task_timeout_secs and blocked for more than 120 seconds problem:

In /etc/sysctl.conf fügte ich folgende Zeilen ein:

...
vm.dirty_background_ratio = 5
vm.dirty_ratio = 10
...

Bis dahin waren folgende Werte aktiv:

# sysctl -a | grep -i dirty
vm.dirty_background_bytes = 0
vm.dirty_background_ratio = 10
vm.dirty_bytes = 0
vm.dirty_expire_centisecs = 3000
vm.dirty_ratio = 20
vm.dirty_writeback_centisecs = 500
vm.dirtytime_expire_seconds = 43200

Danach ein Reboot. Heute trat das Problem nicht auf, aber ich beobachte die Situation weiter.
