Description Marcus Summers 2022-06-09 18:27:28 UTC
Description of problem:
I was trying to open Discord when the application crashed.
SELinux is preventing gdb from 'open' accesses on the file /var/snap/discord/common/fontconfig/0f80fa86029ae75a63f21d682b864529-le64.cache-7.

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

If you believe that gdb should be allowed open access on the 0f80fa86029ae75a63f21d682b864529-le64.cache-7 file 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 'gdb' --raw | audit2allow -M my-gdb
# semodule -X 300 -i my-gdb.pp

Comment 1 Zdenek Pytela 2022-06-10 14:26:30 UTC
It is required to turn this boolean on to allow abrt execute its gdb handler and be able to troubleshoot further:

  # setsebool -P abrt_handle_event on

and subsequently report another bug for the affected component.

Refer to abrt_handle_event_selinux(8) for more information.
Closing as dup of bz#1896648.
