Exit code 139 is a segmentation fault; in this particular context, that basically means that there's been a problem reading from the CD, and the squashfs errors in your logs support that theory. This is generally due to a faulty CD/DVD disk or drive, rather than being an installer bug as such. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, or to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers).
That said, there's a kernel oops in this syslog, which the kernel team should look at. ** Changed in: linux-source-2.6.17 (Ubuntu) Sourcepackagename: ubiquity => linux-source-2.6.17 Status: Unconfirmed => Confirmed -- ubuntu 6.10 installer crashed https://launchpad.net/bugs/97675 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
