The error in your log is: Running postinst hook script /sbin/update-grub. Searching for GRUB installation directory ... found: /boot/grub Searching for default file ... Generating /boot/grub/default file and setting the default boot entry to 0 Searching for GRUB installation directory ... found: /boot/grub Testing for an existing GRUB menu.lst file ... Could not find /boot/grub/menu.lst file. Would you like /boot/grub/menu.lst generated for you? (y/N) n Not creating /boot/grub/menu.lst as you wish User postinst hook script [/sbin/update-grub] exited with value 1 This indicates that you have manually installed the grub1 package (grub) instead of using the default grub2 package (grub-pc) that comes installed with Ubuntu 10.04 LTS. To correct this, run 'sudo apt-get install grub-pc' from the commandline and follow the prompts. ** Changed in: grub (Ubuntu) Status: New => Invalid -- package linux-image-2.6.32-22-generic 2.6.32-22.33 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 https://bugs.launchpad.net/bugs/574110 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
