Thanks for the command output but sadly the error is not the one I'm looking for. To recover could you please open a terminal and run the command: $ sudo dpkg --configure -a
It should configure the remaining packages. If it fails then paste the terminal output. -- package grub-pc 1.98-1ubuntu6 failed to install/upgrade: installed post-installation script alfolyamat 1 hibakóddal kilépett https://bugs.launchpad.net/bugs/587150 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
