Docker not found/working


I can’t seem to get my docker to work after the upgrade.
Can some kind soul point me the right way? I’m a noob at this. Thanks.
I’m hosted on DigitalOcean.



Did you look at How do I debug docker installation issues? Are you running as root?

Maybe reboot?

Did a reboot. Since last night, the screen is just hanging at the Ubuntu loading screen.

Then it’s not a Discourse problem, and likely not a docker problem.

It is likely a hardware issue. Networking might be my guess, but this isn’t going to be the place to get help.

Did the post in the suggested “See:” help any?

Hi guys, I ran it from root.

When I tried to rebuild the app, this is the error presented:

root@forum:/var/discourse# ./launcher rebuild app
/usr/bin/docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "process_linux.go:297: copying bootstrap data to pipe caused \"write init-p: broken pipe\"": unknown.
Your Docker installation is not working correctly


I have tried to remove the docker and then reinstalling it. Same error message as above.
Any help would be appreciated.

What OS are you using?

If you’re in digital ocean, I’d recommend to install a clean 18.04 and start over. Then restore your backup to the new server. 14. 04 if close to end of life anyway.

If you don’t have a backup then you can rsync the discourse directory to the new server and then rebuild. I suspect that digital ocean has a page about rsync.

Thanks @pfaffman.
Happy to have you fix it. I’ll reach out separately via email to you.
