Doc Text:
After digging into SELinux, it seems snapd is the main issue here. Using the software center triggers the snapd update service. As of now, I have not received the update for snapd policies in SELinux. I tried installing the updates manually, but it did not work.

Description Daniel Pettersen 2018-01-11 08:37:39 UTC 
Description of problem:
Installed TopIcons Plus (https://github.com/phocean/TopIcons-plus) when the system reported an error when the extension was enabled. 
SELinux is preventing snapd from 'search' accesses on the directory 6962.

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

If you believe that snapd should be allowed search access on the 6962 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
