UCS 4.2-2 update issue when running "apt list"



My current version is:

UCS Version
4.2-2 errata189 (Lesum)
UMC Version

Please see the list below when I run “apt list --upgradable”. It contains a series of “unknown” entries which is very worrying. Should I ignore this?.
The problem occurred as I ran this command in the process of solving SAML certificate error (see Error checking SAML ucs-sso certificate). I havent yet recieved a reply to this on this forum.

I do not think this is an issue. Please be advised: Only use univention tools to install, upgrade or remove packages, or problems will occur. Only use apt or apt-get directly if advised by our support to do so.

The univention tools you want to use are

univention-install <packages>
univention-remove <packages>

The alternative is to install, remove packages and upgrade your UCS system via the UMC


Thank you. Will stick to that.

I was just experimenting with various suggestions/google-answers to get the SAML SSO certificate error fixed.



That’s one thing you don’t have to worry about. What apt usually lists here is the release a package comes from if that release is known. For Ubuntu, for example, the output might be zsh/xenial,now 5.1.1-1ubuntu2 amd64 [installed]. This requires that the APT repository be set up in a specific way.

A lot of APT repositories use a somewhat simpler setup without real release information. For such repositories apt simply says unknown. Univention’s APT repositories are set up in that simpler mode; therefore all of their packages shown unknown as the release.

This is a technical detail and absolutely nothing to worry about.

Kind regards,
