Maybe yes. The following is the whole story. After fresh installing ubuntu 18.04 to a partition，an error showed up:
"The 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot". After pressing 'ok' the following opened. "Installer crashed" "We,re sorry the installer crashed. After you close this window, we'll allow you to file a bug report using the integrated bug reporting tool. This will gather information about your system and your installation process. The details will be sent to our bug tracker and a developer will attend to the problem as soon as possible" So I googled it and found a solution: cd /tmp/ sudo apt-get download grub-pc-bin dpkg-deb -R grub-pc-bin_2.02-2ubuntu8_amd64.deb grub/ sudo mv grub/usr/lib/grub/i386-pc/ /usr/lib/grub/ sudo grub-install --target=i386-pc --boot-directory=/boot/ --recheck /dev/sdb sudo mount /dev/sdb1 /boot/efi sudo grub-install /boot/efi/ sudo update-grub sudo grub-install --efi-directory=/boot/efi sdb1 is my root partition. After executing the above commands, my laptop rebooted normally. then one day I executed "sudo apt-get dist-upgrade", the bug showed up as described above. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1779560 Title: package shim-signed 1.34.9.1+13-0ubuntu2 failed to install/upgrade: installed shim-signed package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/shim-signed/+bug/1779560/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
