upgrade Script has errors

[RecursiveProgrammer]

Main branch released an upgrade. Tried to run the Upgrade script on the server. Errors displayed.

cat /etc/os-release 
NAME="Ubuntu"

Error log:

sudo ./Ubuntu-Upgrade.sh 2>&1 | tee Ubuntu-Upgrade.sh.log

Ubuntu-Upgrade.sh.log

A few issues: There are special characters in the file that are interfering with the update:

# https://unix.stackexchange.com/questions/27054/bin-bash-no-such-file-or-directory
# correct: 0000000   #   !   /   b   i   n   /   b   a   s   h  \n
head -1 Ubuntu-Upgrade.sh | od -c
000000 357 273 277   #   !   /   b   i   n   /   b   a   s   h  \n
0000017

The following needed to be ran:

sed -i '1s/^.*#/#/;s/\r$//' Ubuntu-Upgrade.sh

The result:

head -1 Ubuntu-Upgrade.sh | od -c
0000000   #   !   /   b   i   n   /   b   a   s   h  \n
0000014

Second issue will be dealing with parsing of the exec path.
