Hi, I found the same problem when try to upgrade to 9.04 RC from 8.10
The problem seem to be that linux image 2.6.28 need to run script call update-grub but on 8.10 it only install grub-common so I try to install grub2 and install the linux image 2.6.28 again then it is o.k. but you can not reboot yet because in menu.lst that to be use by grub still use the UUID format have to change to new grub2 format like (hd0,0) I have to modify /boot/grub/menu.lst inside ther is a line like --> root cef3d6fb-756c-498c-bc5f-6f93bdd2acfb have to change to --> root (hd0,0) then it will boot o.k. otherwise grub will give out error Error 11: Unrecognized device string link below explain more detail about grub2 http://ubuntuforums.org/showthread.php?t=1094723 -- package linux-image-2.6.28-11-generic 2.6.28-11.41 failed to install/upgrade: subprocess post-installation script returned error exit status 2 https://bugs.launchpad.net/bugs/358385 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
