I’ve been using unattended upgrades without any problems until now. However, for the second time, I’m encountering an issue where I end up with a summary stating that some packages were not installed or updated. Among other things, it tells me:
Package imagemagick is held back because a related package is held back or due to local apt_preferences(5).
However, when I run sudo apt full-upgrade, everything is up to date and the packages are installed. sudo apt-mark showhold also doesn’t list any packages. So why am I getting the message that packages were held back?
I would check the term.log/history.log files in the /var/log/apt folder to see if there’s another process installing those updates.
