I seem to have this odd problem with Zorin OS 16.2 specifically. I have tried a few VPN clients and the behaviour is the same. Here's an example:
PIA VPN client - when running this, the app is extremely slow to connect/disconnect. If I reboot the system, I get spammed with a load of bpfilter: read fail 0 and it would take sometimes several minutes for the system to reboot.
Windscribe VPN - The app seems to work ok and is responsive enough however, once again when I reboot, I am spammed with bpfilter: read fail 0 messages and it will take several minutes to reboot.
I should add that this only happens with Zorin OS. I have used countless other distros and I don't have this problem. It has also happened on 2 different Ryzen laptops and the WiFi card doesn't seem to matter as I've tried Realtek and Intel cards. I'm really not sure how to troubleshoot this and would appreciate any pointers. Thank you!
