Apparantly, one needs an Ubuntu SSO account for installing Snaps in 16.04 through ubuntu software (see this link). That's fine with me, but it keeps telling me that my username or password is wrong although I've just changed my password (in fact, twice just to be sure).

So, what could I do to prevent Ubuntu software to tell me my password is wrong, please?

This is a bug caused by the newest version of snapd.

You can work around the problem by opening a terminal and logging in with sudo snap login instead.

    This command (+ my UO email address at the end) works to login, but i still cannot install snaps from GUI or is it only possible through CLI?

  • It is certainly possible to install snaps via GUI. You would need to be more specific about what problem you are encountering after the work around.

Use terminal instead:

~$ sudo snap install vlc vlc (stable) daily from 'videolan' installed
