Just today, after using Calibre with few previous problems, none worth a mention, now I have a problem.

First, this is hthe report from the problem. I hope the "quotes" tags were correct.

calibre, version 6.3.0 (linux, embedded-python: False)

I am using Ubuntu 22.04 abd have no problems with any other news feeds. Go has been reluctant in the past, but this is the first time it has been completely recalcitrant.

I uninstalled Calibre and reinstalled it, but the problem continues.

Does anybody have a solution?

Cheers,
