It seems that you have blindly applied non-universal commits from Debian: https://git.launchpad.net/ubuntu/+source/bash-completion/log/completions/_umount https://git.launchpad.net/ubuntu/+source/bash-completion/log/completions/_umount.linux
while they are not compatible with `mawk`. The `mawk` itself has the same version 1.3.3-17ubuntu3 on 18.04 LTS, 19.04 and 19.10 (see https://packages.ubuntu.com/search?suite=all&exact=1&searchon=names&keywords=mawk ). So it is not the problem. So you should change `mawk` dependency to `gawk` on the Ubuntu side or revert these commits inside `bash-completion`. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1845529 Title: bash completion in 19.10 shows `awk: line 18: function gensub never defined` on ``umount /dev/<Tab>` To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bash-completion/+bug/1845529/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
