Thanks. The crucial section of the log is here: + uname -m + modprobe -q efivars + [ -d /sys/firmware/efi ] + target=i386-pc + source_dir=/usr/lib/grub/i386-pc + [ -d /usr/lib/grub/i386-pc ]
The fact that /sys/firmware/efi does not exist means that your system is not booted under UEFI. That appears to be consistent with the original dpkg log, which says that none of these packages were previously installed. Why are you trying to install grub-efi-amd64-signed? This does not appear to be the correct bootloader for your system. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1223168 Title: package shim-signed 1.3+0.4-0ubuntu3 failed to install/upgrade: el subproceso instalado el script post-installation devolvió el código de salida de error 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1223168/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
