Package: podman
Version: 2.0.4+dfsg2-1
Severity: critical
Justification: breaks unrelated software
Dear Maintainer,
* What led up to the situation?
Installing podman or upgrading from 2.0.2+dfsg1-3 to 2.0.3+dfsg1-1
(transcript below, re-testing with 2.0.4
* What was the outcome of this action?
docker stopped working, in two ways:
- Users in docker group are no longer able to run docker (permission
denied).
- The configured images and containers are no longer available. If they were
running, they still are, but cannot be controlled any more.
This is because /var/run/docker.sock gets unconditionally redirected to
/run/podman/podman.sock.
* What outcome did you expect instead?
Since docker.io is not mentioned in Breaks: and since the packages are not
fundamentally inconsistent, I expect them to work together. This is needed at
least to smoothly transition all configured workloads from one to the other.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Workaround is:
$ sudo dpkg-divert --local --rename --add /usr/lib/tmpfiles.d/podman.conf
$ sudo rm /run/docker.sock
$ sudo systemctl restart docker
Disadvantage is that this restarts any running containers, which might be
undesired at the time.
I suggest creating a podman-docker-compat or similar package with that link,
and also linking /usr/bin/docker to /usr/bin/podman, and breaking docker.io.
