I have not found any specific steps to reproduce this situation so it's somewhat difficult. Anyhow, I've tried to install dapper twice yesterday and there has been no problem at all. It looks OK.
So, Do I need to close this ticket? Can I? What should I do? Please advise me. Thanks! -- Dapper failed to mount disks after upgrade https://launchpad.net/bugs/46189 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
