I am seeing this and I suspect it is because I installed Windows on an extra SSD that was a Linux partition. /dev/sda is that device
``` Setting up grub-efi-amd64-signed (1.155.1+2.04-1ubuntu35.1) ... NTFS signature is missing. Failed to mount '/dev/sda1': Invalid argument The device '/dev/sda1' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around? dpkg: error processing package grub-efi-amd64-signed (--configure): installed grub-efi-amd64-signed package post-installation script subprocess returned error exit status 12 ``` I haven't tried purging the grub package because of the high risk. This seems to be a stale reference to the partition on what used to be a different OS. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871963 Title: dpkg fails to install grub-efi-amd64 signed and shim-signed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/1871963/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
