Exactly, it seems that after fixing all apt-get update related problems and rebooting, I don't get this prompt anymore.
I wasn't sure at first that the new software center was related to apt. I also had a problem with our proxy (apt-cacher-ng) which I had to upgrade from 0.8 to 0.9.1 (backport) on our Debian Jessie proxy server. I still get warnings but not failure about signing keys which I'll fix for our repo but Google's own seems to be problematic too. It seems the new software center should make the user aware of such problem. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-software in Ubuntu. https://bugs.launchpad.net/bugs/1571059 Title: repeatedly ask to download an update when apt index update hits an error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1571059/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
