To use protonvpn i need sudo rights. how do i added this user account to sudo , just for this case ?

@doct0rHu Couldn’t manage to get it ti work. CL i assume uses the values in the file /usr/share/defaults/sudo/sudoers ? I have no idea if anything wriiten in /etc/sudoers will add to those default values as it kept saying that my user name was not in the sudoers file, despite what i believe to be wriiten in the correct syntax. In my Gentoo setup it was possible to use sudo to give root access to one particular program ie Veracrypt .
Anyway it’s not critical at this moment as i can still use NM for ProtonVPN connections.
Thank you for help 
I edited sudoer file with visudo to make sure certain environment variables are kept unchanged. And I don’t have any trouble with that.
Did you edit it with visudo or other editor? It shall not make a big difference but visudo provide syntax checks.
I edited with “EDITOR=nano visudo /etc/sudoers” adding the following line
MY_USERNAME ALL=(ALL) NOPASSWD: /usr/local/bin/protonvpn
I even copied /usr/share/defaults/sudo/sudoers to /etc/sudoers and added the line.
But in both cases my username was not found.
Put it in a file within a /etc/sudoers.d/ drop-in directory instead and it should work.
That worked ! I had wiped ProtonVPN prog , but tested with swupd.
Many thanks for the solution
