Thanks for reporting this bug. This appears to be consistent with how vmbuilder was historically handled - i.e. you can't create a maverick vm using vmbuilder in lucid.
There may be a good reason for it, but I don't know what it is, in particular since this limitation does not seem to hold for debootstrap. Marking this Triaged (as the fix should not be complicated) and Medium priority. The workaround is to use vmbuilder on a natty host. ** Changed in: vm-builder (Ubuntu) Importance: Undecided => Medium ** Changed in: vm-builder (Ubuntu) Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to vm-builder in Ubuntu. https://bugs.launchpad.net/bugs/777331 Title: ubuntu-vm-builder crashed with VMBuilderUserError in preflight_check() -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
