Successfully tested by doing the following: In a fully up-to-date jammy VM:
$ sudo apt -y install libkf5config-bin $ export XDG_CURRENT_DESKTOP=KDE $ export KDE_SESSION_VERSION=5 $ xdg-settings get default-web-browser firefox.desktop $ xdg-settings check default-web-browser firefox.desktop /usr/bin/xdg-settings: 734: Bad substitution Then enabled the jammy-proposed pocket and updated xdg-utils to version 1.1.3-4.1ubuntu1.22.04.1: $ xdg-settings get default-web-browser firefox.desktop $ xdg-settings check default-web-browser foobar.desktop no $ xdg-settings check default-web-browser firefox.desktop /usr/bin/xdg-settings: 734: [: x!: unexpected operator yes The result is as expected in all cases. Note the extra "/usr/bin/xdg- settings: 734: [: x!: unexpected operator" on stderr in the last test. This is not expected, but it is harmless as the output on stdout is as expected. I will report a follow-up upstream bug to get that addressed. ** Tags removed: verification-needed-jammy ** Tags added: verification-done-jammy -- 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 Xdg-utils: Unknown Status in xdg-utils package in Ubuntu: Fix Released Status in xdg-utils source package in Jammy: Fix Committed Bug description: [Impact] The firefox snap (default in 22.04) will always report that it thinks it's not the default browser (even when it actually is) for KDE users (this can be seen when browsing to about:preferences). 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.
