I can confirm this bug in 21.04. However, I think it's about to be coincidentally fixed through the solution to bug #1946499. At least I can successfully open gdebi-gtk in jammy (without passing a .deb file as argument), and if the SRU of the other bug gets completed it ought to be fixed in 21.10 as well.
So since I believe it's fixed in jammy I mark this bug "Fix Released". @corrado: Please add a comment if you disagree on my conclusion, and I'll re-open the bug. ** Summary changed: - gdebi does not start w msg 'Download failed' + gdebi-gtk does not start w msg 'Download failed' ** Changed in: gdebi (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926697 Title: gdebi-gtk does not start w msg 'Download failed' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdebi/+bug/1926697/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
