protonvpn-app fails to start with python error. Missing dependency maybe?

[queenbiscuit311]

The PKGBUILD builds and installs fine, but the program fails to actually work. Here's the terminal output:

  warnings.warn("urllib3 ({}) or chardet ({})/charset_normalizer ({}) doesn't match a supported "

I made sure to install everything from the PKGBUILD, but if that's not the issue then something must be wrong with upsteam I would guess.

Can you try https://github.com/Zylquinal/protonvpn-bin/tree/dep-fix

[Zylquinal]

It works for me, what about you?

[EchterAlsFake]

For me the problem was always that I had some old protonvpn packages installed. Make sure to uninstall them all, delete the python lib files and then reboot your computer before installing protonvpn-bin.

1) sudo pacman -R protonvpn protonvpn-cli protonvpn-gui protonvpn-bin 2) sudo rm -rf /usr/lib/python3.11/site-packages/proton 3) reboot 4) git clone https://github.com/Zylquinal/protonvpn-bin 5) makepkg -si

I can't test it right now, but that's what worked for me in the past.

Tested, and it's indeed caused by old protonvpn version, never use one so i never realize about it.

Can confirm, those instructions fixed it. Thanks!
