Ubuntu Focal update of broken Calibre package

[Norbert Preining]

Hi Julian,

thanks for the guidance, but I am not sure anymore what should be done
and what Ubuntu devs prefer. There was the suggestion of only
backporting the groovy version to focal instead of jumpint to v5.

I guess most Ubuntu devs are busy with the release, but if at some point
you have a bit of air to comment on your preferred option, please let me
know, because I don't want to waste cycles (of both sides) with
preparing a version that will not make it.

Best

Norbert
