Installer looks for the java runtime environment in the wrong folder

[kaasknak]

Hey everyone,

I hadn't played FTB in years and the launcher was having a lot of issues with installing most modpacks so I decided to delete it and reinstall it from the site.
I am running Ubuntu 20.04.
I downloaded the launcher.
Made it executable: chmod +x FTBA_unix_202212152008-a5a6712906-release.sh
Launched the installer: ./FTBA_unix_202212152008-a5a6712906-release.sh
It gets jre.tar.gz without any problems and then crashes giving the following error:

Starting Installer ...
./FTBA_unix_202212152008-a5a6712906-release.sh: 683: /home/username/Downloads/temp/FTBA_unix_202212152008-a5a6712906-release.sh.21214.dir/jre/bin/java: not found

The full log can be found here https://pastebin.com/UnD8pPs2
It notifies me of not finding a java virtual machine but this is also false as when I type java -version
I get:
openjdk version "14.0.2" 2020-07-14
OpenJDK Runtime Environment (build 14.0.2+12-Ubuntu-120.04)
OpenJDK 64-Bit Server VM (build 14.0.2+12-Ubuntu-120.04, mixed mode, sharing)

Kind regards

It seems pretty clear that this project is dead since it also took four days or so before my post even got approved to be viewed publicly.
The solution I found is to download the ATLauncher and install FTB packs via it.
It has been working flawlessly ever since.
