I have experienced the following today.
Has anyone else seen this? Any workarounds to getting openssh-server to install?
So, not incus. Appears to be repository issue for Ubuntu. If anyone else runs into this simply do the following.
apt purge openssh-client
Then openssh-server will install.
apt install openssh-server
I was just going to report this.
It isn’t a repository issue with Ubuntu, it is an image problem with images:ubuntu/24.04. They contain openssh-client version 1:9.6p1-3ubuntu13.7 but that version is only in the noble-proposed pocket. Since the apt sources list do not contain this pocket by default you cannot see the corresponding openssh-server package.
I checked using a VM with LXD installed and their ubuntu:noble image has openssh-client 9.6p1-3ubuntu13.5. It also has openssh-server at that level too. I assume that’s just a difference in choice of packages in the image.
rmadison output:
openssh | 1:9.6p1-3ubuntu13 | noble | source
openssh | 1:9.6p1-3ubuntu13.4 | noble-security | source
openssh | 1:9.6p1-3ubuntu13.7 | noble-proposed | source
That kind of stuff can happen when Ubuntu decides to rollback an update partway through.
You end up with openssh-client preinstalled as a newer version in the image, then openssh-server is the older version causing this issue.
Indeed not Incus specific, you could have hit that on any other Ubuntu system given the right timing.
Ah, ok. I wondered if that was a possibility. I wasn’t sure of the image build process for images:. I suppose it uses distrobuilder and pulls from the repositories?
Yep, exactly and we build those daily, so you probably pulled the image of the day which had a newer openssh at the time it was built, but something went wrong with it and was reverted in the repos afterwards, causing the issue.

That actually shows you that the package was pulled (deleted) from the updates repository.
