Resolving ProtonVPN on linuxmint
Despite following ProtonVPN’s official documentation I want not able to make the GUI app working (loading forever and said Network issue detected or Network error.) whereas the
protonvpn-cli worked right out of the box. It turns out that it is due to some library mismatch but I couldn’t fix.
SystemError: ffi_prep_closure(): bad user_data (it seems that the version \ of the libffi library seen at runtime is different from the 'ffi.h' \ file seen at compile-time)
I sought the help of the support team and it resolved the problem – to remove some
python3 -m pip uninstall cffi argon2-cffi argon2-cffi-bindings
