[CommonLoon102]

Installed from snap store on Ubuntu 23.
Did run with sudo.

Nettop works fine.

If I git clone and cargo build then it works fine.

This issue was briefly mentioned in #314. The SEO on that issue isn't great but here's what I replied quoted:

As of the issue you ran into with snap, I assume it is a permission issue. Process resolution on Linux requires direct access to procfs, which the snap may not have been configured to allow. This is something you'd have to ask Ubuntu packagers to fix.

If you could report this to downstream that would be appreciated, thanks.
