The first installation on this machine is Ubuntu-32 16.04. The problem occurred after installing a 2nd system, Ubuntu-32 18.04 with ubiquity -b and only with apt-get install grub-efi-amd64-signed, not with grub-efi-amd64. After failed installation of grub-efi-amd64-signed the GRUB installation of the 1st system was broken, so I couldn't boot anymore and I had to repair Grub via live-media and chroot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776272 Title: Could not prepare Boot variable: No space left on device (package grub-efi-amd64-signed 1.93+2.02-2ubuntu8 [origin: Ubuntu] failed to install/upgrade: Unterprozess installed grub-efi-amd64-signed package post-installation script gab den Fehler-Ausgangsstatus 1 zurück) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2-signed/+bug/1776272/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
