It's not really useful assigning the bug to Robert without knowing what went wrong, because there's no information to go on for fixing it.

Hopefully this is enough to go on. ** Attachment added: "1716579-bt.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1716579/+attachment/4948607/+files/1716579-bt.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1716579 Title: gnome-software uses a very high cpu amount To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1716579/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
