I have no time currently to look into this, but perhaps one of my co-maintainers will do so. The bug appears after upgrading to python 3.8.3. I have confirmed that calibre 4.13 runs with python 3.8.2 by downgrading using "dnf downgrade python3". I think I have found the source of the bug and it looks to be fixed in calibre 4.15 (https://github.com/kovidgoyal/calibre/commit/7b6416ac6522fc40f24f6baf3ca552b17a8b91d6) The reason it happens after upgrading to python 3.8.3 is that python 3.8.3 added support for abstract socket namespace in the multiprocessing library. (https://bugs.python.org/issue39850) And the line which raises the AttributeError is a workaround for the previous lack of support for abstract sockets. So this bug should be fixable by packaging the newest calibre version (4.17). *** Bug 1841572 has been marked as a duplicate of this bug. *** *** Bug 1840432 has been marked as a duplicate of this bug. *** *** Bug 1840290 has been marked as a duplicate of this bug. *** Could someone try this scratch build: https://koji.fedoraproject.org/koji/taskinfo?taskID=45155009 and confirm it fixes it for you? I'll look at doing an offical build in a bit here... Hi Kevin, it fixes the problem for me. Thanks for the quick fix! (In reply to Suvayu from comment #7) > > Hi Kevin, it fixes the problem for me. Same here. Thanks, Kevin! Great. Official build coming up... thank you !! FEDORA-2020-37c359a64e has been submitted as an update to Fedora 32. https://bodhi.fedoraproject.org/updates/FEDORA-2020-37c359a64e how do I test it please? FEDORA-2020-37c359a64e has been pushed to the Fedora 32 testing repository. In short time you'll be able to install the update with the following command: `sudo dnf upgrade --enablerepo=updates-testing --advisory=FEDORA-2020-37c359a64e` You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2020-37c359a64e See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates. (In reply to william.garber from comment #12) > how do I test it please? If you follow the bodhi link, you will see a command line that's on top of the page. That will install the update for you, then you can check if that resolves the bug and if it's generally functional. You can leave feedback on the bodhi page. When an update is published, it takes about a day to be available in the repositories (see the timestamps on the bodhi page). Hope this helps. it works so far. FEDORA-2020-37c359a64e has been pushed to the Fedora 32 stable repository. If problem still persists, please make note of it in this bug report.
