Jean-Baptiste, that doesn't do it. After my latest update the same happened to me and grub *is* installed.
Good News is, i found out that there is obviously an error in the install script and i was able to fix it the dirty way: The following happened: ... Setting up linux-image-2.6.24-21-generic (2.6.24-21.43) ... Running depmod. update-initramfs: Generating /boot/initrd.img-2.6.24-21-generic Could not find postinst hook script [usr/sbin/update-grub]. Looked in: '/bin', '/sbin', '/usr/bin', '/usr/sbin' ... The problem seems to be the script looking for usr/sbin/update-grub in a directory which is already /bin, /sbin, etc which leads to broken paths like this: /usr/sbin/usr/sbin/update-grub so, i fixed it by creating the above directories and copying /usr/sbin /update-grub there. Voila, update succeeds. Of course this is a very dirty way to fix things but i don't have sufficient knowledge to manipulate the packages and the scripts it contains. This bug will probably affect a lot of people trying to update their system... -- package linux-image-2.6.24-21-generic 2.6.24-21.43 failed to install/upgrade: subprocess post-installation script returned error exit status 1 https://bugs.launchpad.net/bugs/290113 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
