  <p>I think I was something wrong with my intellij installation, since I can't install plugins from the "browse plugins repository" window : no plugin appears.
  I know fundamentals of rights in ubuntu but all files have "lowley" as owner, not "root".
  To install intelliJ I got the .tar.gz from their site, unzipped it (as "lowley") in a subdirectory of "home", and the projects files are in a "home" subdir.
  Please note that I installed java 9 in /opt/java/jdk9, which owner is "lowley".</p>
  
  <p>Here is a screenshot taken from the terminal:</p>
