The following packages have been kept back
There are 3 categories of reasons for packages being kept back during apt upgrade
- It is marked as held back
apt-mark can do this:
sudo apt-mark hold <package>
To list all packages marked on hold or find out if a package is on hold use:
apt-mark showhold
apt-mark showhold <package>
To remove a hold on a package and allow it to be upgraded:
sudo apt-mark unhold <package>
aptdetects a dependency change
This will tell you the current and candidate upgrade versions of the package:
$ apt list <package>
we can figure out the changed dependencies with apt show:
apt show <package>=<old version> <package>=<new version>
The important parts are the Depends and Recommends package lists. If there are new packages in those lists in the new version of the kept back package, apt won't automatically upgrade it
The following security updates require Ubuntu Pro with 'esm-infra' enabled
the file /etc/apt/apt.conf.d/20apt-esm-hook.conf provides the hook that calls the marketing message generation. Removing that is an option[1]
sudo mv /etc/apt/apt.conf.d/20apt-esm-hook.conf /var/tmp
after then run apt upgrade the message does not show
How to cleanly remove x11[2]
sudo apt purge 'x11-*'
sudo apt autoremove
apt-get update “the following signatures couldn’t be verified because the public key is not available”
$ sudo apt update
