This is caused by an upstream bug in xdg-utils (using bashisms in KDE- specific functions whereas the default interpreter is dash). The fix is rather trivial and will visibly improve the UX for those users. [Test Plan] In Kubuntu 22.04: - make sure firefox isn't your default browser (by changing the setting to a different browser) - run the firefox snap, browse to "about:preferences", and observe that firefox claims NOT to be the default browser - click the "Set default" button - refresh the page (F5) - observe that now firefox claims to be the default browser - in a terminal, execute `xdg-open https://example.org`, and verify that the page is open in the firefox snap [Where problems could occur] The patch is changing KDE-specific functions (check_browser_kde and check_url_scheme_handler_kde), so in theory it shouldn't affect running xdg-utils in any other desktop environment. If the proposed patch is incorrect, it would affect the functionality of `xdg-settings check default-web-browser` and `xdg-settings check default-url-scheme-handler`, so this is what needs to be thoroughly tested in KDE. In the event of a regression, these functions wouldn't work as expected (they already don't, so the user wouldn't observe a functional regression, merely the absence of a fix). [Original 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.
