Error when starting up the JTS on a linux machine to run the extension workshop

I'm following the "IBM Rational Team Concert 6.x Extensibility" and I've installed the server side on a Linux VM. I've installed the JazzTeamServer (unziping the file JTS-CCM-keys-Linux64_6.0.6.1.zip) and the server SDK.

When I try to start up the server, I'm geting the following error on ccm.log:

2024-11-06 09:34:28,198 [       Launch callback handler] ERROR eam.repository.provision.internal.ProvisionService  - CRJAZ0288E The "com.ibm.team.rtc.update.site.content.rtc.feature" profile feature could not be installed from the "file:ccm/sites/rtc-commons-update-site" update site that is referenced in the "/tmp/rtc-workshop/install/JazzTeamServer/server/conf/ccm/provision_profiles/rtc-commons-profile.ini" profile file.

Do I need to install the Plain Java Client libs on the server ? What am I doing wrong?

Thanks in advance.
