@CaffeineAddiction why do yu have an "ubuntu" user? If you followed the default installer's procedure you should have had just one user with the username you specified. How did you install Ubuntu?
@ThomasWard If the time a question is posted is a reason for closing it, shouldn't there be a relevant closing/flagging reason? I don't think that no-repro is the right reason for closing such questions and it can be misleading too, both to OP and other users.
@CaffeineAddiction Oh, ok, that makes sense now.
Have you created another user with root privileges? If yes, I suppose that it's safe to delete the "ubuntu" one.
@BeastOfCaerbannog there used to be one. but we're limited to 5 custom reasons, so we're limited on what we can use. The "only relevant to a particular period of time" part of no-repro is still valid, but the actual reason could be adjusted to say "No repro or no longer relevant" - but that's semantics and takes a bit of time to update everything.
