ProtonVPN working - but with issue

Hi guys, I'm wondering if someone will be able to possibly assist with this one. I did a fresh install of Zorin OS, loving it so far.

With a bit of teeth-pulling I managed to get the ProtonVPN CLI installed, and its working BUT I have noticed whenever I run sudo-apt get update, I get the following output concerning ProtonVPN........

'Err:4 stable InRelease
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 71EB474019940E11'

It then says this at the end........

'Reading package lists... Done
W: GPG error: stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 71EB474019940E11
E: The repository ' stable InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.'

Would someone be able to assist in how I can rectify this apparent public key issue?

Thanks in advance for all assistance :slight_smile:

UPDATE: Hi guys, you can ignore this, I managed to get it sorted :smiley:

For others to know the solution, can you say what you did? Did you the apt-key add command?


Sorry for the delayed response, but I think the problem was my own fault. I had installed the beta version of the CLI and followed the wrong instructions. Things went smoother when I started from scratch and read the RIGHT instructions this time.

ProtonVPN for their part when I contacted them, despite me being a paid user politely declined to offer support because I am not using an officially supported distro, which is fair enough. The command line client seems to work ok regardless.

I know that feeling. :smiley: I suspect that this is a common experience. For many, they might search up some symptoms only to realize halfway through reading that the 'solution' they are reading is for Ubuntu 11.04.

I am reminded of the restaurant worker saying, "Only the best ingredients..." Drops the lettuce on the floor. Picks it up and puts it back on the sandwich. "Everything fresh, very fresh..."

A change may bring progress but changes do not mean that progress happened. I do not know how often it is that I look at an online tutorial for something that says to navigate to such and such file and change this line to that line... I look on my computer and that file does not exist.

Sometimes I wish that the Internet could be vetted for relevancy and Posting Date when it comes to installation Guides and tutorials.

On Zorin Os 16, Proton VPN is easier to use.
