If I try to open proton via clicking on the icon,nothing happens whereas if I use the terminal and type protonvpn I get page full of exception and errors.

Traceback (most recent call last):

I have tried reinstalling it, the same issue persists.

UPDATE: I have updated pyopenssl after which the app launched. But now the GUI says "Error Loading Servers" "Nonetype object has no attribute get"

So I checked the log files and found:

2023-01-17 06:02:56,525 — dashboard.py — ERROR —check_if_events_should_be_displayed:221 — 'NoneType' object has no attribute 'get'

maybe you should checkout the dependencies of protonvpn, from protonvpn-nm-lib on github

make sure the packages on your server matches.

The packages match, this issue exists in other apps startup as well. If I try to run pip or ubuntu software and updates on terminal the same error comes up. I think it has to do with some python file dependency but I cant seem to find which one and its difficult to install python packages without pip running.

This happened due to pyOpenSSL package version 22 causing an issue with the cryptography package(2.8). I downgraded pyOpenSSL to version 19 and now proton is running fine.

This caused issues for other apps to launch as well, like software and updates livepatch, ubuntu software center etc, moreover running pip would throw the same error, I had installed pip with the apt package manager with command,

sudo apt install python3-pip

and pip won't work.

Finally, I removed that package and install it via-

$ curl -sSL https://bootstrap.pypa.io/get-pip.py -o get-pip.py
$ python get-pip.py

and this installation was fine since after it pip worked fine and I was able to manage packages easily.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
