I've seen this multiple times over the years, due to how I set up VMs with development release. Last verified earlier right now with the latest Ubuntu Focal live image.
1. On the "Who are you?"-screen, type in your name, for instance "ubuntu". 2. It will autosuggest your computer's name as "ubuntu-Virtualbox" (or machine name on physical machine) 3. The Virtualbox part is uneeded, remove that. 4. Ops, cannot end in a dash. Remove that as well. 5. Tab to the next field. Expected: Everything ok, I pick a username and fill in my password. Actual: When I tab to the username field, I get the error message stating "that name already exists on the network". It stays there until I start filling in my password, or (according to comments above) enough time has passed. ** Changed in: ubiquity (Ubuntu) Status: Incomplete => Confirmed ** Tags removed: quantal vivid ** Tags added: bionic eoan focal trusty xenial -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/924511 Title: ubiquity tells me my computer name already exists on the network - hostname lookup can be slow To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/924511/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
