Upgrade 8.0.4 to 8.0.6 fails: "E: Packages were downgraded and -y was used without --allow-downgrades."

Hi everyone,

We fail upgrading our Cloudron instance on an Ubuntu 22.04.5 LTS machine from 8.0.4 to 8.0.6. I've checked the logs. It seems the updater tries to downgrade some packages while installing Docker, but fails:

Does anybody have any idea on how to proceed?

Thanks for your time!

Oh looks like docker was upgraded then outside of Cloudron updates maybe apt upgrade was called manually in the past.

The installer should have placed the correct versions in /tmp so run the following to manually install the correct version:

apt install --allow-downgrades -y /tmp/containerd.deb  /tmp/docker-ce-cli.deb /tmp/docker.deb

Then the update should succeed again

Thanks, @nebulon—this worked!
