Try this:

https://ubuntu.pkgs.org/21.10/ubuntu...1_all.deb.html

If that does not work then you will have to use the manual install from:
https://calibre-ebook.com/download_linux

Manual binary install

If you wish to revert to an earlier calibre release or download a calibre upgrade manually, download the tarball of that release from here (choose the 32-bit or 64-bit version, as appropriate). Assuming you want calibre in /opt/calibre, run the following command, changing the path to calibre-tarball.txz below as appropriate:

sudo mkdir -p /opt/calibre && sudo rm -rf /opt/calibre/* && sudo tar xvf /path/to/downloaded/calibre-tarball.txz -C /opt/calibre && sudo /opt/calibre/calibre_postinstall

Or do a clean install Ubuntu.
