I am quite lost by you developers on this bug. First, no one seems to have comment on the fact that original poster have nothing to do (as far as I see) related to kernel bug. In fact, I see no usefull errors information in Jarno files except maybe: Oct 10 16:01:24 ubuntu grub-installer: The file /boot/grub/stage1 not read correctly. Oct 10 16:01:24 ubuntu grub-installer: error: Running 'grub-install --no-floppy "(hd0)"' failed. at the end of syslog.
Then, I can only guess you have confirmed Marc Tardif bug about zlib oops that have followed the zlib error: Oct 10 19:53:05 ubuntu python: mkdir /var/lib/ubiquity/source Oct 10 19:53:05 ubuntu python: log-output -t ubiquity losetup /dev/loop1 /cdrom/casper/filesystem.squashfs Oct 10 19:53:05 ubuntu ubiquity: mount: block device /dev/loop1 is write-protected, mounting read-only Oct 10 19:53:05 ubuntu kernel: [17180051.256000] cramfs: wrong magic Oct 10 19:53:05 ubuntu kernel: [17180051.256000] Unable to identify CD-ROM format.

I find this strange, because kamion seemed to consider zlib_fs returned unexpected result 0xfffffffd, as just a faulty disk or faulty drive. In fact, there is other ubiquity bugs with this error, that was not transfrer on linux-kernel (or cramfs), because they did not resulted in a oops. I still find that bug #65106 should not have been used as the one to add duplicates on, because I think Jarno error is not the same. -- oops in zlib_inflate_fast https://launchpad.net/bugs/65106 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
