gnome-software is the correct source package if it is a bug. But the warning message you included in the bug description shows up also when the application launches successfully, so it doesn't help much.
Can you please try to open gnome-software again. If it doesn't launch, then instantly run these commands: sudo apt install apport apport-collect 1596901 ** Changed in: gnome-software (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1596901 Title: gnome-software fail to launch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1596901/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
