I found that SOME repositories don't have the package files for Gnome updates, but some others do. So for me the same symptoms occurred with Gnome updates. Changing my local repository to another one fixed the problem for me. In my case adding deb http://fr.archive.ubuntu.com/ubuntu xenial-updates main solved the problem. Here's a list of mirrors I think work at least with gnome updates: http://packages.ubuntu.com/xenial-updates/all/gnome-software- common/download -- You received this bug notification because you are a member of Ubuntu Studio Bugs, which is subscribed to The Ubuntu Studio Project.

I opened the packages one by one with gnome-software and pressed Install - nothing, except for a super-quick progress bar animation, happened. No matter how many times I tried, same result. Also, an icon pops up on the panel saying "Waiting to install", but nothing seems to happen. This only seems to happen with third-party packages; installing a random deb from packages.ubuntu.com/xenial worked. I even tried to reinstall the system to make this work, but same problem. Gdebi, however, installs the packages as expected.
