I have made the script! You can download it from MediaFire
You’ll have to run the script as root, not by putting “sudo” at the front, but by entering the root environment using “sudo -i” and then running the script using “./upgradeubmate.sh”. You CAN use sudo to run the script, but all the output of the script will come out instead of just text saying what the script is doing.
If you get a “Permission Denied” error when attempting to run the script, enter in “chmod +x upgradeubmate.sh” and then try again.
