title: rstudio-server permission error after upgrade
body: <p>On a VPS with Fedora 23 I recently upgraded my rstudio-server. After this I could no longer login.</p>
  
  <p>After many attempts to repair it I decided to start with a fresh VPS, unfortunately, even here the same problem appears. From <code>systemctl</code> I get:</p>
  
  <pre><code>ERROR system error 13 (Permission denied); OCCURRED AT:
  rstudio::core::Error
  rstudio::core::system::launchChildProcess(std::string, std::string, 
  rstudio::core::system::ProcessConfig,
  rstudio::core::system::ProcessConfigFilter, PidType*)
  /root/rstudio/src/cpp/core/system/PosixSystem.cpp:1297;
  LOGGED FROM: rstu lines 1-13/13 (END)
  </code></pre>
  
  <p>Also:</p>
  
  <pre><code>id -u rstudio-server
  </code></pre>
  
  <p>gives</p>
  
  <pre><code>993
  </code></pre>
  
  <p>I have also set the minimum user id to 100.</p>
  
  <p>Any thoughts would be much appreciated.</p>
