Summary0016256: SELinux is preventing /usr/libexec/snapd/snapd from 'getattr' accesses on the file /proc/<pid>/stat.
DescriptionDescription of problem:
run snap install without sudo (and then enter password interactively)
SELinux is preventing /usr/libexec/snapd/snapd from 'getattr' accesses on the file /proc/<pid>/stat.

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

If you believe that snapd should be allowed getattr access on the stat file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'snapd' --raw | audit2allow -M my-snapd
# semodule -i my-snapd.pp
