Installation in progress - Roundcube package

Hi, I'm using this tutorial.
https://github.com/w2c/ispconfig3_roundcube/wiki/Installation-Instructions-(package)
But in System > Apps & Addon > Packages, I can see all the time:
"Status Package Description local App-ID
server.name.com: Installation in progress
Webmail - Roundcube Installs latest Roundcube with integration to ISPConfig 3 ispapp1 "
server.name.com - name of my server

Any ideas ?
Best
