This issue exists in ubiquity in Natty (dev. branch) I tested natty-desktop-amd64+mac.iso CD (from 2011-03-23).
I entered a username with an underscore, which was not flagged as problematic until I tried to advance to the next screen. The error dialog reappears as soon as it's dismissed, leaving no way to change the username and no way to finish the installation, except to kill ubiquity and restart the install. This problem did not occur just the week before (I cannot recall the ubiquity version) on the same machine when I also installed Natty (dev. branch) and used the same username, containing an underscore. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/407639 Title: Invalid username input creates repeated alerts of invalid username -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
