what's this? everything used to work but now this error won't go away
For no apparent reason I'm now getting this error when starting calibre on my Mint 20 laptop, does anyone know why?

It's Ubuntu publishing broken software as usual. Uninstall the Ubuntu calibre and install the official binaries from https://calibre-ebook.com/download_linux and you will be fine.
