Hello
I am trying to install Guacamole 1.5.5 on to my Ubuntu 24.04 VM.
I followed the instructions in the online document and managed to install
Guacamole server natively by installing all requisite dependencies.
I am encountering an issue with Guacamole client installation.
'mvn package' fails with the following error:
[INFO] Reactor Summary for guacamole-client 1.5.5:
