Public bug reported: I was upgrading my workstation from 19.04 to 19.10 and following that to 20.04. In each case I used do-release-upgrade (without and with -d respectively). The 20.04 upgrade failed as the tool crashed on invalid function signature:
Original exception was: Traceback (most recent call last): File "/tmp/ubuntu-release-upgrader-f_816ncr/focal", line 8, in <module> sys.exit(main()) File "/tmp/ubuntu-release-upgrader-f_816ncr/DistUpgrade/DistUpgradeMain.py", line 238, in main if app.run(): File "/tmp/ubuntu-release-upgrader-f_816ncr/DistUpgrade/DistUpgradeController.py", line 2082, in run return self.fullUpgrade() File "/tmp/ubuntu-release-upgrader-f_816ncr/DistUpgrade/DistUpgradeController.py", line 1998, in fullUpgrade if not self.doDistUpgradeFetching(): File "/tmp/ubuntu-release-upgrader-f_816ncr/DistUpgrade/DistUpgradeController.py", line 1233, in doDistUpgradeFetching self.cache._fetch_archives(self.fetcher, pm) TypeError: _fetch_archives() missing 1 required positional argument: 'allow_unauthenticated' ** Affects: ubuntu-release-upgrader (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1860606 Title: TypeError: _fetch_archives() missing 1 required positional argument: 'allow_unauthenticated' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1860606/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
