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
...
socket(AF_INET, SOCK_DGRAM|SOCK_CLOEXEC|SOCK_NONBLOCK, IPPROTO_IP) = 5
setsockopt(5, SOL_IP, IP_RECVERR, [1], 4) = 0
connect(5, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("127.0.0.1")}, 16) = 0
clock_gettime(CLOCK_REALTIME, {tv_sec=1631995746, tv_nsec=794103764}) = 0

poll([{fd=5, events=POLLIN}], 1, 1000)  = 0 (Timeout)
clock_gettime(CLOCK_REALTIME, {tv_sec=1631995747, tv_nsec=795739261}) = 0
poll([{fd=5, events=POLLOUT}], 1, 0)    = 1 ([{fd=5, revents=POLLOUT}])
sendto(5, "{\311\1\0\0\1\0\0\0\0\0\0\6emeidi\3com\0\0\1\0\1", 28, MSG_NOSIGNAL, NULL, 0) = 28
poll([{fd=5, events=POLLIN}], 1, 1000)  = 0 (Timeout)
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
connect(5, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("127.0.0.1")}, 16) = 0

sendto(5, "UK\1\0\0\1\0\0\0\0\0\0\6emeidi\3com\0\0\1\0\1", 28, MSG_NOSIGNAL, NULL, 0) = 28
poll([{fd=5, events=POLLIN}], 1, 1000)  = 1 ([{fd=5, revents=POLLIN}])
ioctl(5, FIONREAD, [463])               = 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
poll([{fd=5, events=POLLOUT}], 1, 999)  = 1 ([{fd=5, revents=POLLOUT}])
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

ioctl(5, FIONREAD, [278])               = 0
recvfrom(5, "W}\201\200\0\1\0\0\0\0\0\r\6emeidi\3com\0\0\34\0\1\1a\fr"..., 65536, 0, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("127.0.0.1")}, [28->16]) = 278
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

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

Nachtrag: Leider hat diese Einstellungsänderung keine nachhaltige Abhilfe gebracht. Nach einem Umzug trat das Problem übrigens nicht mehr morgens um 4 Uhr auf, sondern abends nach 19 Uhr. Was ich jetzt stattdessen mache: Den RPi zwei Mal am Tag neu booten (um 5 Uhr, sowie um 17 Uhr). Das hat effektiv geholfen, das Problem tritt nicht mehr auf.

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.

Mit upower den Batteriestatus von Linux-Laptops überwachen und aufzeichnen

upower ist ein sehr nützliches Kommandozeilen-Tool, wenn man sich für den Batteriestatus seiner Linux-Laptops interessiert (Linux-Server meiner Wahl: Lenovo Thinkpads).

Ich verwende es auf zwei Arten (Anleitung zum Schnellstart):

  • Alarm wenn auf Batteriebetrieb geschaltet wird Ein cron-Script schreibt den Status der Batterie alle fünf Minuten in eine Datei. Die Datei wird von monit überwacht. Wenn das Gerät (1) auf Batteriebetrieb schaltet (wegen Stromausfall, oder weil das Stromkabel ausgezogen wurde) und (2) die Ladung der Batterie unter einen vordefinierten Grenzwert sinkt (aktuell: weniger als 80 Prozent), erhalte ich von monit regelmässig eine Meldung per Email. In einem Fall konnte ich so aus der Ferne zuschauen wie die Batterieladung kontinuierlich abnahm, bis dass Gerät offline ging.
  • Aufzeichnung mit cacti Die von upower ausgegebenen Vitaldaten speise ich in cacti ein, um den Verlauf der Vitaldaten darstellen zu können. Was ich derzeit aufzeichne: Verbleibende Maximalkapazität der Batterie in Prozent der Design Capacity, Ladung Batterie in Prozent, Ladung der Batterie in Wh, Ausgangsspannung, Ausgangsleistung („Draw“).

Problem

Der Parameter energy-rate (Dokumentation) …

Amount of energy being drained from the source, measured in W. If positive, the source is being discharged, if negative it’s being charged.

… enthält bei einigen Laptops plausible Werte …

...
# OPENVPN 1
energy-rate:         4.761 W
...
# OPENVPN 2
energy-rate:         3.298 W
...
# ELK (Elasticsearch Lucene Kibana)
energy-rate:         21.288 W
...

… bei anderen Laptops nicht:

...
# Web-Server
energy-rate:         0.00409639 W
...

APT meldet für packages.cloud.google.com NO_PUBKEY

...
Err:10 http://packages.cloud.google.com/apt cloud-sdk-stretch InRelease
  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 8B57C5C2836F4BEB NO_PUBKEY FEEA9169307EA071
...

Die Lösung:

# curl https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -

Quelle: NO_PUBKEY error in google cloud debian packages update

ACHTUNG:

  • Auf eigene Gefahr: Man sollte Ausgaben mit curl nie an lokale Kommandos pipen …
  • Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

Das nervende „You have mail.“ beim SSH-Login loswerden

Gestern habe ich auf allen meinen Linux-Systemen /etc/motd geleert, um bei SSH-Logins kein grosses Login-Banner mehr angezeigt zu bekommen.

Jetzt aber ist mir auf verschiedenen Systemen die folgende Zeile markanter ins Auge gestochen:

Linux GRIFFINDOR 4.9.0-12-amd64 #1 SMP Debian 4.9.210-1 (2020-01-20) x86_64
You have mail.
Last login: Thu Apr  1 15:13:36 2021 from 10.1.2.3

Wie wird man diesen Hinweis los? Ganz einfach:

  1. $ mail
  2. d1-%Anzahl Emails in INBOX%
  3. q

Quelle: Safely get rid of “You have new mail in /var/mail” on a Mac?

Der Befehl d1-100 weist mail an, die ersten hundert Emails zu löschen. q bedeutet „quit“.

Supports Wake-on: pumbg

Kürzlich habe ich nachgeschaut, welche meiner Lenovo ThinkPad Linux-Server Wake-on-LAN (WOL) aktiviert haben.

Dies überprüft man mittels des folgenden Kommandos:

# ethtool eth0
...
        MDI-X: on (auto)
	Supports Wake-on: pumbg
	Wake-on: g
        Current message level: 0x00000007 (7)
...

Doch was bedeutet pumbg?

p   Wake on PHY activity
u   Wake on unicast messages
m   Wake on multicast messages
b   Wake on broadcast messages
a   Wake on ARP
g   Wake on MagicPacket™
s   Enable SecureOn™ password for MagicPacket™
d   Disable (wake on nothing). This option clears all previous options.

Quelle: Wake on LAN unter Linux

Schön. Jetzt muss ich nur noch überprüfen, ob die Laptops auch wirklich hochfahren, wenn ich ihnen im ausgeschalteten Zustand ein WOL-Paket sende.

Mit apt-get auf eine bestimmte Paket-Version downgraden

Gestern habe ich ohne lange zu Überlegen Kibana auf meinem ELK-Server gelüpft. Schlechte Idee:

{"type":"log","@timestamp":"2021-02-11T23:20:13+01:00","tags":["error","savedobjects-service"],"pid":501,"message":"This version of Kibana (v7.11.0) is incompatible with the following Elasticsearch nodes in your cluster: v7.10.0 @ 10.1.2.3:9200 (10.1.2.3)"}

Abbruch, zurückbuchstabieren — aber wie?

Zuerst überprüft man, was die letzte funktionierende vorherige Version war:

$ apt-cache madison kibana

    kibana |      7.3.1 | https://artifacts.elastic.co/packages/7.x/apt stable/main amd64 Packages

    kibana |      7.2.1 | https://artifacts.elastic.co/packages/7.x/apt stable/main amd64 Packages
    kibana |      7.2.0 | https://artifacts.elastic.co/packages/7.x/apt stable/main amd64 Packages
    kibana |      7.1.1 | https://artifacts.elastic.co/packages/7.x/apt stable/main amd64 Packages
    kibana |      7.1.0 | https://artifacts.elastic.co/packages/7.x/apt stable/main amd64 Packages
    kibana |      7.0.1 | https://artifacts.elastic.co/packages/7.x/apt stable/main amd64 Packages
    kibana |      7.0.0 | https://artifacts.elastic.co/packages/7.x/apt stable/main amd64 Packages

Somit muss ich versuchen, 7.10.2 über 7.11.0 zu installieren. Doch wie macht man das?

# apt-get install kibana=7.10.2

Und damit beim nächsten Lauf Kibana 7.11.0 nicht erneut installiert wird, benötigt man noch einen Eintrag in /etc/apt/preferences:

...
Package: kibana
Pin: version 7.10.2
Pin-Priority: 1001
