HI getting this error message when trying to install:
��<�pre>The following packages have unmet dependencies: python3-proton-vpn-session : Breaks: python3-proton-vpn-api-core (< 0.20.2) but 0.20.1 is to be installed E: Unable to correct problems, you have held broken packages. <�/pre>
Any help would be appreciated!
What OS and version are you trying to install on? Copy/Paste the /etc/os-release file contents would be simple 
ETA: How are you trying to install (command)?
Not an expert, but I did have some initial trouble getting Proton installed on Ubuntu 22.04
I’m in Ubuntu 22.04 used the commands the snap install said to use - I will find them again and post.
You can install it straight from flatpak.
