Thanks for releasing a fixed package. BUT, could you consider using a release version of calibre instead of a development version at a kind of random state. I see, that at the time focal was released there was no 5.x version available, but meanwhile official 5.x releases are.
For a LTS version it's IMHO not a good idea to go with a development version, where other bugs might be still in or there might be a good chance calibre plugins are broken with this version. In the ubuntu dev list https://lists.ubuntu.com/archives/ubuntu-devel/2020-October/041236.html the debian caliber maintainer provided a 5.2 version for focal. I'm using it since he released it and it works fine. Source and amd64 packages are available there: deb http://www.preining.info/debian focal main deb-src http://www.preining.info/debian focal main Could you consider using this (or another 5.x version) instead? -- You received this bug notification because you are a member of Edubuntu Bugsquad, which is subscribed to calibre in Ubuntu. https://bugs.launchpad.net/bugs/1898904 Title: Calibre crashes at startup with AttributeError: 'NoneType' object has no attribute 'cancel' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/calibre/+bug/1898904/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~edubuntu-bugs Post to : edubuntu-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~edubuntu-bugs More help : https://help.launchpad.net/ListHelp
