I had it again on upgrade of another system from 14.04 to 16.04 I used: do-release-upgrade -d
/boot/efi ws mounted ro for some reason. The line in fstab is: UUID=a369305d-809f-3317-8484-01d6c86315c5 /boot/efi auto defaults 0 3 - the file system was not dirty - mount -o remount,rw /boot/efi failed with no logging or explanation get-around: mount | grep /boot - note device, mount point and options umount /dev/sda1 # the device mount -o relatime,umask=22,uid=0,gid=0,nls=utf8 /dev/sda1 /boot/efi # options less the ro, device and mount point The installer on continue will display: Could not install the upgrades The upgrade has aborted. Your system could be in an unusable state. A recovery will run now (dpkg --configure -a). Setting up fwupdate (0.5-2ubuntu4) ... Installing fwupia32.efi to EFI system partition. Setting up fwupdate-signed (1.11+0.5-2ubuntu4) ... Upgrade complete The upgrade has completed but there were errors during the upgrade process. To continue please press [ENTER] Suggested fix: if fwupdate notices /boot/efi being ro, print this fact and wait for ENTER key. - the user can then in another terminal fix the problem -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1573160 Title: package fwupdate 0.5-2ubuntu4 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fwupdate/+bug/1573160/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
