When I pass the device it shuts up.. OKAY .. my initial report was bug 1872097 my original and still existing install partition (sda5) for focal ( dec 2019) I used dpkg-reconfigure there and of course then debconf-get-selections did not give the correct info ..
So I created a new partition (sda6) on the drive using existing free space and manually installed focal there as a second instance using a recent (03/28) iso (xubuntu). This was a not connected to network install as my wireless net work driver is not on the install disk (rtl8821ce-dkms) (installed via a brief chroot prior to first boot) also on the drive are windows 10 partitions at sda1,sda3,sda4 plus sda2 which is the /boot/efi (EFI) partition. (always mounted to /boot/efi so far as I know by default) SDA6-order of events: I booted into the fresh install (after network driver was installed). I did the first upgrade on sda6 using the software updater after running the language updater which appeared first. During this install the grub-efi-amd64-signed setup threw up a window complaining the partition sda2 had changed or did not exist.. It had one check box for proceeding .. and a continue button .. then a second message appeared with some thing that looked like this: grub-efi /dev/sda2 device ?? parition ?? changed or does not exist hovering over this gave a message about systems without a bios or in a vm being etc. grub not being needed also that I might not be able to boot if I did install There were two buttons to continue or not-install(?).. I chose to not install .. so the /boot/efi entries remained the same as first installed. Then I installed debconf-utils and then ran debconf-get-selections as directed in comment #2 output as in comment #5 Then I rebooted to partition sda5 and tried to reinstall it as the primary start-up Comments 6,7,8) trying to overwrite the /boot/efi (/dev/sda2 [EFI]) partition so my normal boot would be directly into the main xubuntu install on sda5. output in comments #6 most of output) and #7 (with the omitted last line) I then ran the commands in comment #8 .. checked the time stamps on the /boot/efi partition and they had changed .. I hope this clarifies things. so it is easy to reproduce this bug .. with and older fresh install of ubuntu (xubuntu) focal just do it networkless on a computer with a windows 10 install -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872077 Title: package grub-efi-amd64-signed 1.140+2.04-1ubuntu24 failed to install/upgrade with mount: /var/lib/grub/esp: special device /, does not exist To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2-signed/+bug/1872077/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
