Description Leonardo Avellar 2017-12-31 19:00:59 UTC
Description of problem:
Was trying to update my system and the snapd package popped on SELinux Troubleshooter
SELinux is preventing snapd from 'read' accesses on the directory /var/cache/snapd.

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

If you believe that snapd should be allowed read access on the snapd directory 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 'snapd' --raw | audit2allow -M my-snapd
# semodule -X 300 -i my-snapd.pp
