I have been booting with the same version of UEFI from Asus since April. But now either UEFI or Ubuntu is deleting all UEFI entries and creating multiple new UEFI entries from boot device.
I was having issue of UEFI entry not installing at all. fred@bionic-z97:~$ sudo grub-install --bootloader-id ubuntu /dev/sda --recheck Installing for x86_64-efi platform. Could not prepare Boot variable: No space left on device grub-install: error: efibootmgr failed to register the boot entry: Input/output error. I have to boot full install on flash drive and use configfile to boot into working install in sda. But something is adding entries from flash drive's ESP. And on reboot added a second BIOS/grub entry (which is not used) I can see UEFI entries come from flash drive as it has extra bionic & copy folders. I was then able to add an entry for working install on sda, but reboot erased it. After boot with efi_not_storage_paranoia And reset of UEFI to defaults & changing back to my preferred settings fred@bionic-z97:/media/fred/ESP_USB/EFI$ ll total 24 drwxr-xr-x 6 fred fred 4096 Apr 4 15:34 ./ drwxr-xr-x 4 fred fred 4096 Dec 31 1969 ../ drwxr-xr-x 3 fred fred 4096 Mar 10 17:47 bionic/ drwxr-xr-x 2 fred fred 4096 Apr 21 09:36 Boot/ drwxr-xr-x 3 fred fred 4096 Apr 21 09:37 ubuntu/ drwxr-xr-x 3 fred fred 4096 Apr 2 12:43 'ubuntu (copy)'/ fred@bionic-z97:/media/fred/ESP_USB/EFI$ sudo efibootmgr -v -c -L ubuntu -l \\EFI\\ubuntu\\shimx64.efi efibootmgr: Warning : Boot0000 has same label ubuntu efibootmgr: Warning : Boot0001 has same label ubuntu efibootmgr: Warning : Boot0002 has same label ubuntu efibootmgr: Warning : Boot0003 has same label ubuntu BootCurrent: 0004 Timeout: 1 seconds BootOrder: 0005,0002,0001,0000,0004,0003 Boot0000* ubuntu HD(1,GPT,2a6f47aa-0ae8-42e3-86d8-6463449b2862,0x800,0xfa000)/File(\EFI\ubuntu\shimx64.efi) Boot0001* ubuntu HD(1,GPT,2a6f47aa-0ae8-42e3-86d8-6463449b2862,0x800,0xfa000)/File(\EFI\bionic\shimx64.efi) Boot0002* ubuntu HD(1,GPT,2a6f47aa-0ae8-42e3-86d8-6463449b2862,0x800,0xfa000)/File(\EFI\ubuntu (copy)\shimx64.efi) Boot0003* ubuntu VenHw(99e275e7-75a0-4b37-a2e6-c5385e6c00cb) Boot0004* UEFI: (FAT) PciRoot(0x0)/Pci(0x1d,0x0)/USB(1,0)/USB(5,0)/HD(1,GPT,2a6f47aa-0ae8-42e3-86d8-6463449b2862,0x800,0xfa000)..BO Boot0005* ubuntu HD(1,GPT,3195d314-ce88-42ac-beac-d9f80289ac11,0x800,0xf9dcd)/File(\EFI\ubuntu\shimx64.efi) fred@bionic-z97:~$ sudo efibootmgr -v [sudo] password for fred: BootCurrent: 0002 Timeout: 1 seconds BootOrder: 0002,0001,0000,0004,0005,0003 Boot0000* ubuntu HD(1,GPT,2a6f47aa-0ae8-42e3-86d8-6463449b2862,0x800,0xfa000)/File(\EFI\ubuntu\shimx64.efi) Boot0001* ubuntu HD(1,GPT,2a6f47aa-0ae8-42e3-86d8-6463449b2862,0x800,0xfa000)/File(\EFI\bionic\shimx64.efi) Boot0002* ubuntu HD(1,GPT,2a6f47aa-0ae8-42e3-86d8-6463449b2862,0x800,0xfa000)/File(\EFI\ubuntu (copy)\shimx64.efi) Boot0003* ubuntu VenHw(99e275e7-75a0-4b37-a2e6-c5385e6c00cb) Boot0004* UEFI: (FAT) PciRoot(0x0)/Pci(0x14,0x0)/USB(9,0)/HD(1,GPT,2a6f47aa-0ae8-42e3-86d8-6463449b2862,0x800,0xfa000)..BO Boot0005* ubuntu VenHw(99e275e7-75a0-4b37-a2e6-c5385e6c00cb) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1787692 Title: package grub-efi-amd64-signed 1.93.4+2.02-2ubuntu8.3 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/1787692/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
