ProtonVPN certificate errors and installation process procedures

[acew1zard]

I follow the guide and I HAVE THE LATEST VERSION of Ubuntu:

Does any one here have protonVPN running on their computer? I get an error related to certificate error. Why?I got this error before and no one was able to help so I THINK does that mean no one uses protonVPN? I clicked the .deb file an it launched and ran/installed in the local software package manager, then I ran the terminal commands and instantly I got the above error messages. I am somewhat new to Linux and not that smart so please forgive me but this is the only truly free VPN service out there and is a very popular one so I think this is important.

I also get this error when I try to install and setup up mongodb. I don't know what is going on at this point. Please any help will suffice because this is important.

EVEN when I modify the sources files and do it for clouddb I Get the same error. I think ubuntu devs need to know about this so we can fix it together. How do I report a bug to the dev community.
