We have another issue related to docker not upgrading because of unmet deps.

Check journalctl -fa and if it shows something like below over and over again:

The following packages have unmet dependencies: docker-ce : Depends: libseccomp2 (>= 2.3.0) but 2.2.3-3ubuntu3 is to be installed E: Unable to correct problems, you have held broken packages.

To fix:

apt update

You might have to run the above command a couple of times since it might says it cannot get the lock. Once the update is done, it should update automatically.

@girish Done ! Thank you ! 😄

Wanted to post the known important issues so far:

Invalid aliases causes an internal error. https://git.cloudron.io/cloudron/box/issues/533 External domains are not migrated properly. When an app used an external domain in 1.x, this was moved as a "manual" domain in 2.x. If you try to enable email for this migrated domain, you will hit https://git.cloudron.io/cloudron/box/issues/525. Workaround is in the bug report.
