Re: [Bug 1707832] Re: package shim-signed 1.32~16.04.1+0.9+1474479173.6c180c6-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1
Hi Steve, The computer still boots successfully! So now I have two directories in /boot/efi/EFI, one called "ubuntu" and the other called "Ubuntu 16.04.2 LTS". 1. Would you recommend I remove the older Ubuntu 16.04.2 LTS directory? 2. Do you think this problem will occur again for future updates? Some more info: The ubuntu directory has a plist file in it that says product version 2.02~beta2-36ubuntu3.12 The Ubuntu 16.04.2 LTS directory has a plist file in it that says product version 2.02~beta2-36ubuntu3.9 When I boot the computer it only shows the newer version 2.02~beta2-36ubuntu3.12. Thank you very much for your help!

Hi Steve, I followed your instructions and copied /boot/efi/EFI/Ubuntu 16.04.2 LTS/mach_kernel to /boot/efi/EFI/ubuntu/mach_kernel I then installed grub manually using a modified command from same guide I referred to earlier sudo grub-install --target x86_64-efi --boot-directory=/boot --efi-directory=/boot/efi --bootloader-id="ubuntu" The install succeeded!
