Your password is probably for "sudo" operations, not
for becoming root itself. Does root even have a password? (/etc/passwd,
and /etc/shadow should tell you that).
The wiki says root is disabled as standard in ubuntu. I am not allowed
to open shadow.

K3b won't write first or second time or it I wait a while.
Looking at K3bSetup via sudo and password, it checks the devices
(PHILIPS CDRW/DVD SCB5625 in /dev/scd0 and /dev/sg1) and gives ther old
permissions as 660 root.cdrom and the new permissions as 666 root.cdrom
with no obvious facility to change the permissions beyond that.
Mark said:
I still feel the comment I made before about the disk either needing
time to
be detected once you choose burn or perhaps media incompatability is
most likely.
If that is so, why does it accept a file by drag and drop once only - at
least in GNOME? (dragging and dropping does not work in KDE) And
attempting to open it in KDE it says there is a malformed url.
I am tempted to reinstall with the later 7.04. If I do so, presumably I
should copy back /home - should I uninstall 6.06 first - if so, how?
Unless you can suggest a command line approach to changing the
permissions using sudo. Then perhaps I can upgrade via the standard
ubuntu method.
Many thanks to everyone who has responded
