The log shows: Running postinst hook script /sbin/update-grub. Searching for GRUB installation directory ... found: /boot/grub Searching for default file ... found: /boot/grub/default 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) Not creating /boot/grub/menu.lst as you wish User postinst hook script [/sbin/update-grub] exited with value 1 Your bug report shows this system was originally installed as 10.04, which installs grub2 by default; but the error message indicates you have uninstalled grub2 and installed grub instead. Please correct this by running 'sudo apt-get install grub-pc' from the commandline. ** Changed in: grub (Ubuntu) Status: New => Invalid -- package linux-image-2.6.32-22-generic 2.6.32-22.36 failed to install/upgrade: il sottoprocesso vecchio script di post-installation ha restituito lo stato di errore 1 https://bugs.launchpad.net/bugs/589986 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
