Comment 4 for bug 755355

Thank you for your kind response. I ran "sudo apt-get clean" & ran
update manager...There was no detectable or visible response. I may be
able to throw some light on the issue though?

I have three hard drives on the same machine, Windowsxp, Maverick 10.1,
and Natty Beta 1.

I always keep the outgoing distro (mav) until the final release of the
new distro is relatively bug free or stable.

Maverick uses the Geode driver with ATI 2400 HD pro; while Natty is now
using the newly supplied ATI fglrx driver's which was a major problem as
Natty default driver hangs at boot time and you cannot see the monitor
to pull in a new driver . Natty needs a driver choice at pre-install.

My problem. For Natty boot time I ran "sudo update-grub" which gave
error message, [357.007452] EXT-fs (sdg1) write access unavailable,
cannot proceed. I then re-booted and ran Maverick with "sudo
update-grub" I then got the error message [170.504403] EXT-fs
(sdc1)write access unavailable, cannot proceed.

Grub seems to be incompatible with the two competing distros; at boot
time there was several old headers present so I ran "dpkg -l 'linux-*'
| sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\
+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo
apt-get -y purge" to clean them.

I hope this helps you comprehend the issue...many thanks Chris.
