I am trying to upgrade to 18.04 using
sudo do-release-upgrade -d, but it exits the installation with the message:
Calculating the changes EFI System Partition (ESP) not usable Your EFI System Partition (ESP) is not mounted at /boot/efi. Please ensure that it is properly configured and try again. Restoring original system state Aborting
I have Windows on this machine as dual boot. Fast boot is disabled on Windows 10.
I have tried to mount it in GParted but the option is disabled...
What should I do to be able to move forward?
