Stephen, there is no package called 'software' but one called gnome- software which is provided by default in all GNOME based distributions and one called ubuntu-software which is a transitional package in later Ubuntu releases.
The default software store in Ubuntu 20.04 is actually a snap called snap-store which should appear in program menus as 'Software'. I think that is what you are probably using in which this case this bug report needs to be moved to the 'snap-store-desktop' project. I've seen this problem myself when using a non-default theme in Xubuntu. Are you using a non-default theme in Ubuntu? If so, does the problem go away when using the default Yaru theme? ** Changed in: 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/1886295 Title: Ubuntu 20.04:software installer on gui has no background - very hard to see, a lot of faulty installs going on To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1886295/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
