Hi guys
In UCS 5.03 the current version of docker is 19.03.8, newest 23.0.0. Do we know the plan for when will be updated to at least to 20.0.0 version?
Thanks
As UCS 5.03 is build on Debian Buster the Version 20 of docker is first implemented in Debian Bullseye so the Version 20 will come in Summer with the Buster to Bullseye Upgrade on UCS i think

Thank you very much 
Actually we use docker from Ubuntu 20.04 as it was way newer than the version in Debian-10-Buster when UCS-5.0-0 was released. Nevertheless no (major) update is planned as they include incompatible changes, which might break other use-cases.
The next UCS will be based on Debian-12-Bookworm, which is scheduled for this summer. It will then contain an updated version of docker, too.
It’s an old post but somehow I suspect it getting more urgent with the perspective of UCS 5.2 being released someday in 24.
If I understand right, it is not advised to install docker from the docker-repo?
Although https://github.com/fbartels/univention-bitwarden is some time ago, it was still working on UCS until only recent: https://github.com/dani-garcia/vaultwarden/issues/3872
The only way to update vaultwarden is to update docker.
Best, Bernd
Only the version of docker shipped with UCS 5.0 is tested and guaranteed to work with UCS. If you update to a newer version you risk breaking UCS Apps. Univention Support will most likely refuse to support such systems. It might probably work, but do that only on your own risk.
PS: docker consists of multiple inter-dependent binary packages, which other packages also depend on. They might have incompatible changes so you might easily end up in a situation where those dependencies cannot be satisfied as they conflict.
