I updated UEFI from Asus, but same version I was using since April. Still only can boot with rEFInd from sdc or flash drive with full install of Ubuntu.
UEFI does not want to see ESP on sda which is mounted by fstab. It changes entries to like drive disconnected. And on reboot all new entries only from ESP on sdc are created. But ran dosfsk on ESP at sda1, and it showed error with dirty bit set, as soon as I rebooted so shutdown was not correct. Also tried manually unmounting my ESP at sda1 and immediately shutting down, but same issue. UEFI would not see ESP on sda1 and dirty bit set again. And all new entries in UEFI from sdc's ESP files. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1753518 Title: package grub-efi-amd64-signed 1.93+2.02-2ubuntu8 failed to install/upgrade: installed grub-efi-amd64-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/grub2-signed/+bug/1753518/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
