Debian: Repository changed its ‚Codename‘ value

Heute verweigerte apt-get seinen Dienst:

# apt-get upgrade
...
Reading package lists... Done
E: Repository 'https://dl.ubnt.com/unifi/debian stable InRelease' changed its 'Codename' value from 'unifi-5.14' to 'unifi-6.0'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.

Das Problem löst man, in dem man vor apt-get upgrade folgenden Befehl ausführt:

# apt-get update --allow-releaseinfo-change
