You don't have a source for libqt5quickwidgets5 which is needed by
protonmail-bridge.  There's no point trying to resolve the trickier
problems if we know we're going to end up at a dead end without
libqt5quickwidgets5.

So you need to upgrade to an Ubuntu or other distro version which
contains at least libqt5quickwidgets5.

When you do so your other problems may or may not magically go
away, but at least you won't be wasting time in a dead end.
