Problem upgrading from CD and ISO

[Jason Spaceman]

I'm trying to upgrade Ubuntu 8.04 to 8.10 via the alternate CD. I downloaded the CD, burned it to a disc and tried to run 'sudo cdromupgrade', but I get the following error:


snozzy@loonix:/media/cdrom$ sudo ./cdromupgrade
tar: ./dists/stable/main/dist-upgrader/binary-all//intrepid.tar.gz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error exit delayed from previous errors
Could not find the upgrade application in the archive, exiting

I get the same error if I try to mount the .iso file and run 'sudo cdromupgrade'. What am I doing wrong? It seems to be complaining about not being able to find 'intrepid.tar.gz', but that file is on the disc. Did Ubuntu screw up and put a '//' where just '/' should have been?

Are you able to access that file manually? There might have been an error in the download that renders the file unreadable.

Yeah, this is what the cdromupgrade file contains:


snozzy@loonix:/media/cdrom$ cat cdromupgrade
#!/bin/sh
#
# "cdromupgrade" is a shell script wrapper around the dist-upgrader
# to make it possible to put it onto the top-level dir of a CD and
# run it from there
#
# Not that useful unfortunately when the CD is mounted "noexec".
#
# WARNING: make sure to call it with a absolute path!
# (e.g. /cdrom/cdromugprade)

# the codename is AUTO-GENERATED from the build-host relase codename
CODENAME=intrepid
UPGRADER_DIR=dists/stable/main/dist-upgrader/binary-all/

cddirname="${0%\/*}"
fullpath="$cddirname/$UPGRADER_DIR"

# extrace the tar to a TMPDIR and run it from there
if [ ! -f "$fullpath/$CODENAME.tar.gz" ]; then
echo "Could not find the upgrade application archive, exiting"
exit 1
fi

TMPDIR=$(mktemp -d)
cd $TMPDIR
tar xzf "$fullpath/$CODENAME.tar.gz"
if [ ! -x $TMPDIR/$CODENAME ]; then
echo "Could not find the upgrade application in the archive, exiting"
exit 1
fi
$TMPDIR/$CODENAME --cdrom "$cddirname" $@

I wonder if it is the same as this bug. (https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/277873)
