slightly modified
from openwrt without installing ubuntu to the mmc…
You still need to make sure your uboot is updated per the instructions on github.

fdisk /dev/mmcblk1
select g
select w
fdisk /dev/mmcblk1
select n

hit enter till your done
select w

mkfs.ext4 /dev/mmcblk1p1
mkdir /mnt/sd
mount /dev/mmcblk1p1 /mnt/sd
cd /tmp
curl -SL http://download.gl-inet.com/firmware/mv1000/ubuntu/testing/ubuntu-18.04.3-20191109.tar.gz -o /tmp/ubuntu-18.04.3-20191109.tar.gz

tar -xf /tmp/ubuntu-18.04.3-20191109.tar.gz -C /mnt/sd

from openwrt run:
fw_setenv image_part 1
fw_setenv image_dir /boot/
fw_setenv fdt_name armada-gl-mv1000-ubuntu.dtb
fw_setenv args_sd setenv bootargs root=/dev/mmcblk1p1 rw rootwait
fw_setenv bootscript run boot_sd
reboot

if you want to go back to openwrt you can:
dd if/dev/zero of=/dev/mtd1

thank you.
also is it possible to extract to a subdirectory of sdcard-root
I.E. mkdir /mnt/sd/newdir
tar -xf /tmp/ubuntu-18.04.3-20191109.tar.gz -C /mnt/sd/newdir
and then boot from it by
I.E. fw_setenv args_sd setenv bootargs root=/dev/mmcblk1p1/newdir rw rootwait

so as to hold multiple OS testing configs

Well not for the root device but you can add an additional partition , for example for arch Linux and Ubuntu I have mmcblk1p1 as / for Ubuntu and mmcblk1p2 for arch
