Your upgrade log says: > No such font or not readable by grub: /boot/grub/unicode.pf2GRUB_GFXMODE=1024x768

You will need to correct this file to finish your upgrade. ** Package changed: grub (Ubuntu) => grub2 (Ubuntu) ** Changed in: grub2 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1349118 Title: package linux-image-3.5.0-44-generic 3.5.0-44.67~precise1 failed to install/upgrade: el subproceso instalado el script post-installation devolvió el código de salida de error 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1349118/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
