This is already fixed on master via https://github.com/containers/libpod/pull/4692/files Fixed in podman 2.0 which will be released in 8.3 release. Closing as this is fixed in an upcoming release. Assigning to Jindrich so he can handle any packaging needs. Mike Burns - Please confirm that we have agreement from OSP to delay 1841485 until RHEL 8.4, Apr-2021. It is not clear from the recent comments that everyone on OSP has agreed that is OK. I can't find fixed version podman-2.1.1-4 in brew system, please update
fixed version if it indeed doesn't exist.

Description of problem: When something kills a running podman exec, we leave a stray ExecIDs for that container which then makes it impossible to remove the container without an "rm -f".
