Public bug reported: (This is on xenial, but I've had similar problems on bionic as well).
The docker.io package was updated last night (via unattended-upgrades), and this morning I could no longer start containers, the error message being: docker: Error response from daemon: failed to start shim: exec: "docker-containerd-shim": executable file not found in $PATH: unknown. To get it to work again I - pruned all stopped containers - restarted dockerd - restarted containerd Not sure if all of these steps were needed. An issue like this seems to pop up basically whenever the docker.io package is updated. ** Affects: docker.io (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1836022 Title: Cannot start containers after docker.io update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1836022/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
