I suppose that would work (although I haven't actually tested to confirm, but it looks correct and I'm trusting your shell-fu). The real questions are:
* why is this working in stock Ubuntu (where /bin/sh is also a symlink to dash) and not in Kubuntu? * why does the upstream project declare /bin/sh as the default interpreter for xdg-settings, yet use bash-specific string manipulation functions? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xdg-utils in Ubuntu. https://bugs.launchpad.net/bugs/1970594 Title: "xdg-settings check default-web-browser something.desktop" fails in Kubuntu 22.04: Bad substitution Status in kubuntu-meta package in Ubuntu: New Status in xdg-utils package in Ubuntu: Confirmed Bug description: I'm reporting this issue from stock Ubuntu, but the problem is observed only in Kubuntu (can be reliably reproduced in a Kubuntu 22.04 VM). The version of xdg-utils is identical. This problem was initially reported on the snapcraft forum: https://forum.snapcraft.io/t/firefox-wont-set-as-my-default- browser/29708. $ xdg-settings check default-web-browser firefox_firefox.desktop /usr/bin/xdg-settings: 734: Bad substitution The offending line is: if [ x"!" == x"${browser:0:1}" ]; then If I modify /usr/bin/xdg-settings in place to set the interpreter to /bin/bash on the first line of the script, the problem goes away.
