snap login expects an email as argument (not a username). So the output you get is the response from SSO complaining you didn't provide a valid email address. We need to improve that error message.
If you try: $ snap login your_sso@email it should work (and request your 2FA if you have it enabled). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1587181 Title: snap login prompts for password but login fails To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1587181/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
