I have not been able to verify this after installing the package and starting bash again. I even went as far as a reboot.

Things to look out for as a regression would be if another previously-working completion would fail to work (ie. what if mount stops completing correctly, and works again if the fix is backed out?). --- ProblemType: Bug DistroRelease: Ubuntu 19.10 Package: bash-completion 1:2.9-1ubuntu1 ProcVersionSignature: Ubuntu 5.3.0-10.11-generic 5.3.0-rc8 Uname: Linux 5.3.0-10-generic x86_64 ApportVersion: 2.20.11-0ubuntu7 Architecture: amd64 CurrentDesktop: MATE Date: Thu Sep 26 18:46:59 2019 Dependencies: InstallationDate: Installed on 2019-09-26 (0 days ago) InstallationMedia: Ubuntu-MATE 19.10 "Eoan Ermine" - Beta amd64 (20190926.1) PackageArchitecture: all SourcePackage: bash-completion UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bash-completion/+bug/1845529/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
