Description Ian Laurie 2021-02-24 23:58:00 UTC
Description of problem:
Logged into Xfce from the greeter.
SELinux is preventing avahi-daemon from 'open' accesses on the file /proc/<pid>/environ.

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

If you believe that avahi-daemon should be allowed open access on the environ 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 'avahi-daemon' --raw | audit2allow -M my-avahidaemon
# semodule -X 300 -i my-avahidaemon.pp

I am having this on 4 virtual machines and one native machine (all my fc34 test machines have this issue with latest selinux-policy-3.14.7-25.fc34.noarch).
