E-book viewer fail with Ubuntu 22.04
After an upgrade to Ubuntu 22.04 I found out that the e-book viewer (Calibre 5.41) is not working anymore.
Code:
ERROR: Render process crashed:
The Qt WebEngine Render process has crashed
The problem doesn't occur if I install Calibre 5.37 from from Ubuntu default repository.

I've searched how to turn off qt web engine and found out this one:
Quote:
This can be worked around by running Calibre and its associated applications with:
QTWEBENGINE_DISABLE_SANDBOX=1
But this is an ugly hack and seems to have a few ill effects on the running of Calibre on Ubuntu 22.04.

Heh, I posted the same thing here:

https://www.mobileread.com/forums/sh...d.php?t=333116

So...how do I turn it off? i tried passing that as a parameter to Calibre but it had no effect. And if it's broken on Ubuntu, perhaps it should be turned of by default? I understand it's the most popular distro.

Going back to the one in the Ubuntu repo fixes it but it's probably a 14 year old version of Calibre!

Its an environment variable, google how to set environment variables system wide in linux if you dont know how to do it. Or wait for the next calibre relase which sets it for you automatically if it detects you need it.

Ah, ok I'll give that a go. I assumed that was a Calibre tweak, not a global qt thing.
