Per https://bugzilla.redhat.com/show_bug.cgi?id=1840780#c2 this happens
on python >= 3.8.3. As Focal ships 3.8.5 we get this bug. Juanjo linked
and attached the upstream patch already, which is included in Calibre >=
4.15. Focal ships Calibre version 4.99.4 which I assume is some pre-
release versi
As a work-around for those affected, I can confirm that manually
applying the upstream patch to
`/usr/lib/calibre/calibre/utils/ipc/server.py` does allow Calibre to
start up successfully.

I have uploaded a patched version of calibre to a ppa:

It works for me. It should work as an interim until there is an updated
package in the official Ubuntu repository.

Hello grofaty, or anyone else affected,
Accepted calibre into focal-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/calibre/4.99.4+dfsg+really4.12.0-1ubuntu1
in a few hours, and then in the -proposed repository.
Please help us by testing this new pack
Thanks for releasing a fixed package.
BUT, could you consider using a release version of calibre instead of a
development
version at a kind of random state. I see, that at the time focal was released
there
was no 5.x version available, but meanwhile official 5.x releases are.
For a LTS versio
Let's fix the immediate problem first, then someone can file a new bug
and do the proper procedure to try and get a newer version into focal
and groovy.

When this started to happen? I would be surprised if it was an update to
focal (why?), but I have the feeling this was working at the beginning.
