description |
When installing from an iso file, with grub's loopback option, Ubiquity displays a message stating the isodevice cannot be unmounted, even when the isofile is not located on the same harddrive as the installation target.
sudo umount -l -r -f /isodevice
solves this problem, so Ubiquity should be able to issue this command by itself, without any user action.

How to quickly reproduce :
- From a Linux distro installed (Ubuntu 18.04 here)
- Install grml : sudo apt install grml-rescueboot
- Get Focal iso : wget -0 /boot/grml/focal.iso http://cdimage.ubuntu.com/daily-live/current/focal-desktop-amd64.iso
- add toram option : echo ' CUSTOM_BOOTOPTIONS="toram" ' | sudo tee -a /etc/default/grml-rescueboot
- Generate the Grub entry : sudo update-grub
- Reboot and select the Grub entry for the iso
- Start the Ubuntu installation : Ubiquity ask if it should try to umount /isodevice - You accept - But patitioning fails anyway .
See https://help.ubuntu.com/community/Grub2/ISOBoot for more info

-----Solution ---------------
Before starting ubiquity :
sudo umount -l -r -f /isodevice
sudo losetup -d /dev/loop1
You can then install Ubuntu and partition your disk like if you were on USB !
