Re: apt-upgrade (Bullseye) shows 1 pkg not upgraded

Hello,

If for example you have set up unattended-upgrades and installed apt-
listbugs, then when unattended-upgrades runs, apt-listbugs
automatically pins (-30000) upgradable packages that are affected by
bugs in order for them to be hold until a fix. They are automatically
de-pinned when bugs are fixed. Such pinned packages appear in
/etc/apt/preferences.d/apt-listbugs
(look at apt-listbugs manpage for details)
