Description milas.robin 2024-05-26 06:48:42 UTC
One of my flatpak program crash regularly, as it does I get a SELinux error each time from systemd-coredump probably trying to access information inside the flatpak

=====================================================================
SELinux is preventing systemd-coredum from using the sys_admin capability.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that systemd-coredum should have the sys_admin capability by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'systemd-coredum' --raw | audit2allow -M my-systemdcoredum
# semodule -X 300 -i my-systemdcoredum.pp
