Facing the same problem on a fresh 16.10 installation, experienced it first while trying to install VLC through software centre. Ubuntu SSO GUI didn't log me in, I tried a workaround using Terminal:
~$ sudo snap login <email> [sudo] password for abhishek: Password: Login successful abhishek@kabhishek:~/Documents$ sudo apt-get install vlc Only the GUI SSO option doesn't authenticate. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-software in Ubuntu. https://bugs.launchpad.net/bugs/1616943 Title: Can't auth against U1 in g-s Status in gnome-software package in Ubuntu: Fix Committed Status in gnome-software source package in Xenial: Triaged Status in gnome-software source package in Yakkety: Fix Committed Bug description: [Impact] Authentication using Ubuntu One credentials to install/remove snaps always fails. This is due to a behaviour change in snapd (no longer accepts login requests from non-root users). Existing credentials continue to work. [Test Case] 1. Delete any existing credentials by deleting passwords marked "com.ubuntu.UbuntuOne.GnomeSoftware" using Seahorse. 2. Start GNOME Software 3. Search for a snap (e.g. "moon-buggy") 4. Install Snap 5. Enter Ubuntu One credentials when prompted Observed result: Dialog says "Incorrect email or password". Expected result: Authentication completes and the snap is installed. [Regression Potential] The solution is to use a new D-Bus service (snapd-login-service) and new library (snapd-glib) to get the Macaroon from snapd. This has some risk of introducing new bugs. The change is minimised (other snapd code paths unchanged) and the alternative is login to be impossible.
