Version 4.4.0-5 didn't need the "reinstall iputils-ping" delta so apparently this got fixed somewhere else (thanks Sergio for figuring this out and syncing). The Debian d/changelog has:
backuppc (4.4.0-5) unstable; urgency=medium [ Simon McVittie ] * debian/rules: Specify canonical path to ping6. (Closes: #992647) That Debian bug is about a *different* issue, but maybe using the canonical path somehow made a difference, who knows. Speaking of Focal (the only open task here): we should verify if the same change fixes the issue there. The autopkgtest is hinted there, so this is non-blocking. I'm setting the Focal status to Incomplete for now as the whole issue is in my opinion not well understood. ** Changed in: backuppc (Ubuntu Focal) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1936437 Title: Backuppc autopkgtest fails doing ping6 due to 'Operation not permitted' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/backuppc/+bug/1936437/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
