Basically what xdg-open does with $BROWSER is to set it if and only if it's unset. If it's set, it should be a colon separated list of possibilities, starting with x-www-browser. Instead, in our case, it's equal to qupzilla only. That said, something outside of xdg-open is setting it to qupzilla, so it's not xdg-open.
It's also not falkon. I was thinking maybe there were some remaining references left in the postinst to qupzilla, but it is not the case. If BROWSER was unset, it would be set to x-www-browser and the postinst of falkon does set it as x-www-browser, so we'd be done. Unfortunately, it's already set. So maybe that's a bug against xdg-open that it doesn't do anything if it's already set, but I don't think so. That said, your hint was a good one, as it gets to the heart of the problem (the value of BROWSER) but the solution is not obvious. We could add a BROWSER setting to falkon's postinst but that would really be sort of strange. None of firefox, chromium-browser, konqueror, epiphany or w3m do this. I think it would be better if we find the cause and remove it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1786986 Title: ubuntu-bug fails trying to open qupzilla browser To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lubuntu-default-settings/+bug/1786986/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
