sudo fdisk -l /dev/sda /dev/sda1 EFI System
/dev/sda2 Linux filesystem
/dev/sda3 Linux swap[/code][/quote]
sudo mount /dev/sda2 /mnt
sudo mount /dev/sda1 /mnt /boot/efi
for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done
sudo chroot /mnt #Error after this command
Error after command: chroot: failed to run command '/bin/bash': Exec format error
ldd /bin/bash gives a list of dependent libraries
There are many instructions on the Internet, but chroot ends in each I have this error, but I did not find a solution.
A 64-bit ubuntu image was used, and the 2nd generation VM does not allow running 32-bit systems.
