This was committed to ufw a while ago and will be in the upcoming 0.36, which I plan to SRU back to bionic.

According to /usr/share/bash-completions/bash_completion, which defines the helper functions: # Backwards compatibility for compat completions that use have(). # @deprecated should no longer be used; generally not needed with dynamically # loaded completions, and _have is suitable for runtime use. and at the end of the file: unset -f have unset have which means: function have() is not available for usage. The bash completion for ufw conditionally defines _ufw and the comspec: have ufw && _ufw() ... [ "$have" ] && complete -F _ufw ufw These should be changed to: _have ufw && _ufw() ... _have ufw && complete -F _ufw ufw ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: ufw 0.35-5 ProcVersionSignature: Ubuntu 4.15.0-22.24-generic 4.15.17 Uname: Linux 4.15.0-22-generic x86_64 ApportVersion: 2.20.9-0ubuntu7.1 Architecture: amd64 CurrentDesktop: XFCE Date: Mon Jun 4 14:34:11 2018 InstallationDate: Installed on 2018-04-28 (37 days ago) InstallationMedia: Xubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) PackageArchitecture: all SourcePackage: ufw UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ufw/+bug/1775043/+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
