Ive looked into it but can not realy find the issue. Im no Guacamole user myself. Probably best if you ask in related forums what the issue might be. It installs fine and i do not see a issue with the scripts so far. Sadly i can not provide deeper help for every app in the repository. If you end up finding the error and it is related to how we install Apache Guacamole, let me know and i Update the Script acordingly!

can everyone try to use an debian or ubuntu vm and enter the install functions of -install.sh? (without STD)

Work this?
Otherwise we remove guacamole completely.

Hi everyone,
Thank you for your responses and for looking into the issue. I will investigate further on my side to identify what might be causing this problem. If I manage to find a solution or pinpoint the root cause, I will provide feedback here so it can potentially help resolve the issue in the script or its configuration.

If in the build script you can leave an option for selecting a version, it may be beneficial. I tried several different methods to get it working and I couldn't get it going. Finally I tried installing version 1.5.3 (current is 1.5.5) and everything works. The race condition bug was introduced in 1.5.4, there is an alleged work around, which I could not get working.
