Hi there,
I am currently out of the country, and silly as I am, I wanted to update my discourse server - usually that goes without issues.
After the update, the forum didn’t come back up. I tried git pull and launcher rebuild but this error keeps coming up:
/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
Searching the forum didn’t yield much - other than “Your docker isn’t working”. I didn’t change a thing, and the machine itself is dedicated for Discourse. I tried reinstalling docker, but nothing changed…
Any help to get the forum up and running again will be greatly appreciated 
It’s running Ubuntu 14.04.5 LTS on Digital Ocean (I wasn’t sure if it was safe to upgrade to 16.04)…
From the thread I ran:
root@forum:~# docker run --rm -i -a stdin -a stdout ubuntu echo 1
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.
Docker version:
# docker -v
Docker version 18.06.2-ce, build 6d37f41
