Hello @Kopax_Anderson,
I can’t be sure but I am suspecting that you installed the scanner in a location where the scanner has no write access. When ran, the scanner downloads on a local cache the plugins from SonarQube.
The local cache location is by default $HOME/.sonar
You can relocate the cache location by setting the environment variable $SONAR_USER_HOME to a location the scanner will be able to write. Can you check if that fixes your problem.
