Ubuntu 22.04.01 LTS
Gnome

Changed python version which resulted in inability to access Terminal and a few other things.

Used a liveUSB and then selected to try ubuntu.

In that terminal entered:

sudo fdisk -l

sudo mount /dev/sda1 /mnt/

sudo mount --bind /proc/ /mnt/proc/

sudo mount --bind /sys/ /mnt/sys/

sudo mount --bind /dev/ /mnt/dev/

sudo cp /etc/resolv.conf /mnt/etc/resolv.conf

sudo chroot /mnt/

That code executed fine.
I then wanted to change python3.11 to python 3.10 with

sudo update-alternatives  --set python /usr/bin/python3.6

However I get the error listed in the title. Other attemps with various code to change python also raise the same error. Can't find any similar questions on here.
