Container fails to (re)start after system update

Installation
1

Hi,

I upgraded my server (debian 8.5) a few days ago via apt-get. docker-engine was updated. I use docker only for discourse. The discourse container did not restart after updating. Manually restarting fails with

/var/discourse# ./launcher restart app
/usr/bin/docker: Error response from daemon: rpc error: code = 2 desc = “shim error: invalid argument”.
Your Docker installation is not working correctly

See: Troubleshoot docker installation issues

The link provided does not help or I don’t understand. I found some threads around here and tried

/var/discourse# git pull
./launcher rebuild app

but this failed with the same result.

Thanks for any help on how to fix or debug this.

What does docker version and docker info report? Docker needs to be installed, ideally updated to latest, and working.

Hmm, not sure. That looks roughly correct, but clearly something is not right with your Docker. Maybe remove Docker and re-install?

did not help. same issue :frowning:

Are you on bare metal or some kind of hidden VM? I’ve heard horror stories from being on shared VPSes using certain types of cheap virtualization with Docker… it just doesn’t work.

I am not sure. The server is definetly just a virtual machine but I did not feel any restraints so far and discourse was working nicely for some months now just like some other (non docker) apps, that still work fine.

Meanwhile I also did

rebuild app

again after re installing docker. So now it should be all fresh, or is there anything else I could try to reset (without losing data)?

Nope, without a functioning Docker you are pretty hosed.
