fc25 - Gnome
When I try to install any app from gnome-software, I get the following message:
Detailed errors from the package manager follow:
installing not available
I had previously masked packagekit, because it was downloading while I was trying to get on the Internet. I then unmasked it and added packagekit to Gnome Extension "Services systemd." I think I turned it off once; but have left it on ever since.
Any suggestions appreciated.
