Hi all, When trying to install Proton VPN in Kali Linux, I encountered the following errors:

Errors 'GnuTLS: error in pull function' &
'Unable to establish SSL connection' 

Request code from terminal

Can anyone help fix it?

upd: I apologize to everyone for the inconvenience, but if anyone encounters a similar problem, it is solved by enabling VPN. I first downloaded the first VPN I could find for my browser, then downloaded another VPN via terminal, ran it there, re-entered the command to download Proton and everything downloaded without any problems.

Ensure that the ca-certificates package is installed and up to date.

sudo apt install ca-certificates
sudo update-ca-certificates

ca-certificates is already the newest version (20240203).

Packages are updated, any other suggestions where to dig? Can it be related to the fact that ProtonVPN site is blocked in my country?
