0. Sign in with “snapcraft login” if you aren’t signed in already. 1. At the command line, enter “snapcraft register Firefox”. 2. Enter “y”. What happens: ------------  😌 11:15:27@~> snapcraft register Firefox We always want to ensure that users get the software they expect for a particular name. If needed, we will rename snaps to ensure that a particular name reflects the software most widely expected by our community. For example, most people would expect ‘thunderbird’ to be published by Mozilla. They would also expect to be able to get other snaps of Thunderbird as 'thunderbird-$username'. Would you say that MOST users will expect 'Firefox' to come from you, and be the software you intend to publish there? [y/N]: y Registering Firefox. The name 'Firefox' is not valid. It can only contain dashes, numbers and lowercase ascii letters. ------------ What should happen: If the name is not valid, only the error message should appear. The babble and question about people expecting the name should not appear. [Originally mentioned by Kyle Fazzari in bug 1644673.]
