I am trying to install LTIB on my Ubuntu machine and getting the following error:
```
$./install
You are about to install the LTIB (GNU/Linux Target Image Builder)
Before installing LTIB, you must read and accept the EULA
(End User License Agreement) which will be presented next.
Do you want to continue ? Y|n
Y
Hit enter to continue:
sh: 1: Syntax error: "(" unexpected
I have read and accept the EULA (yes|no):
yes
sh: 1: Syntax error: "(" unexpected
Use of uninitialized value $_ in pattern match (m//) at ./install line 139.
Cannot extract release tag at ./install line 140.
```
How to resolve this issue?
Any help is appreciated.
