On a Intel NUC with a fresh Ubuntu Server 22.04.1 LTS installation I failed to install docker according to these instructions. Step:

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

gave the following error:

Job for docker.service failed because the control process exited with error code.
See "systemctl status docker.service" and "journalctl -xeu docker.service" for details.
invoke-rc.d: initscript docker, action "start" failed.

See also similar topic without a solution mentioned.

I found my solution in disable blocking of my pi-hole (possible a VPN could also create this error)
Perhaps this will help someone during installation

had the same issue. opened up synaptic and saw docker-ce-rootless packages were not uninstalled from previous setup. removed those and reinstalled again. that fixed my problem.

The logs shows that iptables parameter is invalid.
Here’s my case:
12月 09 17:07:20 rock-5b dockerd[11123]: time="2022-12-09T17:07:20.968713872+09:00" level=warning msg="Running iptables --wait -t nat -L -n failed with message: `iptables v1.8.7 (nf_tables): Could not fetch rule set generation id: Invalid argument`, error: exit status >

I found the solution to fix this here;
iptables v1.8.7 (nf_tables): Could not fetch rule set generation id: Invalid argument · Issue #140 · P0cL4bs/wifipumpkin3 (github.com)

Run this command. This fixed my case.
update-alternatives --set iptables /usr/sbin/iptables-legacy
