I have been running a gitlab-ce server at home via the docker image for a few years. Recently I started receiving errors on my git push and pull requests. It seemed to have started around the 15.8.1 release (after I upgraded my instance). I am seeing this as the only this error in the logs:
chroot(“/run/sshd”): Operation not permitted [preauth]
I redeployed my container instance and the issue is still there. I have upgraded to 15.9 and still having the same issue.
