Cloudron down after Ubuntu/Docker update (Docker service fails to start)
-
my claude chat if it helps

For what its worth, the issue occurred for me last Thursday night after using the reboot option in the dashboard, as instructed by the typical Cloudron notification. The VPS came back up, but the Cloudron dashboard was unreachable. In the VPS terminal, the troubleshooter showed docker was not starting. Two additional VPS reboots did not resolve it, so I simply rolled back, and then everything appeared to be working.
Later that night, Cloudron updated from 9.1.5 to 9.1.6.
When another reboot notification appeared yesterday, I took another snapshot of the VPS before rebooting, and everything came back up just fine.
However, I did NOT delete my cloudron.conf file, and it still exists.
My docker version is 29.1.5, build 0e6fee6.

Hello @valexico
So, should we do something to restore our cloudron to nominal configuration ? Recreate this cloudron.conf file somehow ?
That would be best I think.
If this would reproduce the previous issue, that be interesting to get an understanding what is causing this.The default content from
/etc/systemd/system/docker.service.d/cloudron.confis:[Service] ExecStart= ExecStart=/usr/bin/dockerd -H fd:// --log-driver=journald --exec-opt native.cgroupdriver=cgroupfs --storage-driver=overlay2 --experimental --ip6tables --userland-proxy=false -
hi @james
I tried to restore this file but docker won't start.
Claude analysis :
- systemd (file
cloudron.conf) passes--log-driver=journald - But /etc/docker/daemon.json also defines log-driver:
json-file
So what is the official fix ?
Here are some logs :
