Resolved Docker doesn't start after upgrade to Debian 11

[fhe]

Server operating system version

Debian 11.4

Plesk version and microupdate number

18.0.45.2

I've updated from Debian 9 to Debian 11 using the recommended steps and everything worked fairly okay. Except for one thing where Docker doesn't start anymore. Using systemctl start docker produces this output in journalctl -xe and I don't know how to proceed.

Clicking the Docker tab in Plesk gives "Error: Connection refused".

Any help is very much appreciated!

My guess is that it's related to AUFS not supported on Bullseye which I now read in the release notes.

Note that Debian 11 is not listed as a supported OS for Docker in Plesk: Using Docker

OK, thank you. I wish I had seen this earlier and I'm even not sure if this this still valid or just outdated documentation.

As I understand, support for Debian 9 was dropped by Plesk starting with 18.0.45 so it'd be great if Docker would be supported with the current supported OS versions.

Hello,
For my part, Docker works fine on Debian 11.4 and Plesk Obsidian v18.0.45, so, I guess the documentation is outdated.
After that I couldn't tell you exactly the problem, for my part, it's on a "fresh installation" with the basic installation offered by Plesk.

Thank you! I've now removed the Docker extension, reinstalled, and have setup the containers from scratch and now it's working here to.

However, I'm getting an update notification when running apt list --upgradable and now I'm unsure if it's safe to upgrade:

# apt list --upgradable
Listing... Done
containerd.io/bullseye 1.6.6-1 amd64 [upgradable from: 1.4.3-1]
docker-ce-cli/bullseye 5:20.10.17~3-0~debian-bullseye amd64 [upgradable from: 5:19.03.15~3-0~debian-stretch]

Do you have those latest versions running on your system?
