Hi Lukasz,

so, here are a few more answers to your questions:

Yes. I just installed a vm, updated to the latest version of the
packages of focal, installed calibre, started calibre, and got

norbert at ubuntu2004-vm:~$ calibre
Traceback (most recent call last):
  File "/usr/bin/calibre", line 20, in <module>
    sys.exit(calibre())
  File "/usr/lib/calibre/calibre/gui_launch.py", line 73, in calibre

  File "/usr/lib/calibre/calibre/gui2/main.py", line 543, in main
    listener = create_listener()
  File "/usr/lib/calibre/calibre/gui2/main.py", line 514, in create_listener
    return Listener(address=gui_socket_address())

    self._listener._unlink.cancel()

So well, it is completely useless.

There are not autopkgtests, but there is an extensive test suite built
into calibre.

Since it does not even start, I guess there is no regression for
focal users, only for those upgrading from a previous release.


Together with YOKOTA Hiroshi (in Cc), who has done most of the work on
recent packaging, I have prepared a version for focal (SIP4, debhelper
12), built it on my focal machine, and successfully run it. Source and
amd64 packages are available here:

	deb http://www.preining.info/debian focal main
	deb-src http://www.preining.info/debian focal main

(signed with my gpg key https://www.preining.info/rsa.asc)

What are the next steps you are expecting from me?

- prepare a package for groovy and separately for focal?
- what are the version numbers you want to see?
- how should we proceed?

Best

Norbert
