I don't think that the hardware was the source of the problem, since I've installed the final iso with the same cdrw and the same cd drive. Other people have seen this bug too.
Marking the bug as fix released (it works fine now). ** Changed in: debian-installer (Ubuntu) Status: Unconfirmed => Fix Released -- debootstrap: cannot execute mount (Xubuntu daily 20060928) https://launchpad.net/bugs/62770 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
