The name is not exactly the same, which one you want me to delete...

The protonvpn-stable.list is all you need to delete, but I would remove the protonvpn-stable.list.save to be thorough.

Later in the other thread, I posted Proton's guide for installing - but if that is not working, then the GPG key error is something only they can correct as the package maintainers.
All you can do is remove the repository for now - or request the correct GPG key directly from them and add it yourself.

Oh I'm just realizing, on the right click I don't have the delete option, not even cut!

If using the GUI, did you launch the file manager as Root?

sudo -i

nautilus

Other locations > Computer > /etc/apt/sources.list.d

7

Didn't change, this is the terminal response

fernando@fernando-Alienware-m17-R4:~$ sudo -i
[sudo] password for fernando:
root@fernando-Alienware-m17-R4:~# nautilus

These can be ignored, since those are user specific and stored in ~Home not in Root. They will appear if Nautilus is launched in Root.

Right click context menu has no "send to Trash" or "Delete" at all?

9

No, and 'send to' only opens an email message...

10

Can you close that all out.

Launch Nautilus (Files) normally.
Tap ctl+l (That is control + L) to pull up the addressbar
Enter if admin:///etc/apt/sources.list.d

It should PW prompt, then allow you in folder - see if the context menu works by this route.

Yes sir, I have to continue later, thankful for your precious support so far!

You could as alternative delete it in the Terminal, too. The Commands are:

sudo rm /etc/apt/sources.list.d/protonvpn-stable.list

sudo rm /etc/apt/sources.list.d/protonvpn-stable.list.save
