[Podman] Re: Podman hanging on start, ps, and erroring out with slirp4netns on run

Hi Matt, Seems I forgot to include transcripts of me kill those processes. Even though I do kill the processes and try to run again, it still hangs. Doing podman ps after killing the processes works, but starting my bitwarden container just doesn't got anywhere no matter if I kill all processes or restart - it always hangs. For slirp4netns I had 0.3.0-2.git4992082.fc30. Upgrading to 0.4.0-4.git19d199a.fc30 did make podman run work, and testing on that new container seems to work fine. Would my bitwarden container be corrupted somehow? spytec@KeyraGuest1:~$ podman run -p 5432:5432 -d --name test postgres d73a11bc83b1de7811b8a6eb393e7c7de2ea98dda968ae11c4b490b1c16eb444 spytec@KeyraGuest1:~$ podman ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES d73a11bc83b1 docker.io/library/postgres:latest postgres 8 seconds ago Up 3 seconds ago 0.0.0.0:5432->5432/tcp test spytec@KeyraGuest1:~$ podman stop test d73a11bc83b1de7811b8a6eb393e7c7de2ea98dda968ae11c4b490b1c16eb444 spytec@KeyraGuest1:~$ podman start test test spytec@KeyraGuest1:~$ podman start bitwarden ^C On Fri, 31 Jan 2020 at 15:33, Matt Heon <mheon(a)redhat.com&gt; wrote: > On 2020-01-31 15:11, Eric Gustavsson wrote: > >Hi all, > > > >I have unit file generated by podman running, though as soon as I run it > >there's issues with running any other command that needs to do something > >with containers. podman ps for example will be completely unresponsive > and > >not return anything, even after waiting minutes.
