Hi, I have successfully installed Rstudio server (open source) on VM located on Ubuntu 16.04.2 LTS in the institute cluster. I can access the URL on port 8787. But when I try to sign in to Rstudio using my username and password, it processes for few seconds and then shows the following:

RStudio initialization error: unable to connect to service

I did not get any error when I ran command 'sudo rstudio-server verify-installation'. But when I checked `/var/log/syslog` which shows the following:

ERROR system error 13 (Permission denied) [path=/home/biology/.rstudio, target-dir=]; OCCURRED AT: rstudio::core::Error rstudio::core::FilePath::createDirectory(const string&) const /home/ubuntu/rstudio/src/cpp/core/FilePath.cpp:826; LOGGED FROM: int main(int, char* const*) /home/ubuntu/rstudio/src/cpp/session/SessionMain.cpp:3303

PS: R version 3.3.2 (2016-10-31); rstudio-server-1.0.136-amd64.deb

Suggestions please.

Thanks!
