I was following the OpenCPU manual for installing their server (https://opencpu.github.io/server-manual/opencpu-server.pdf, sec 2.2) and everything was installing fine and at the last step I got this message:

Adding opencpu user account usermod: no changes Creating log files... Taking ownership of system directories... Making scripts executable... Considering conflict mpm_event for mpm_prefork: Considering conflict mpm_worker for mpm_prefork: Module mpm_prefork already enabled Enabling opencpu in apache... Reloading apparmor... Restarting apache... Installation done! Failed to execute operation: No such file or directory Setting up libprotobuf-dev:amd64 (2.6.1-1.3) ... Processing triggers for libc-bin (2.23-0ubuntu9) ...

I have bolded the part I am worried about, did the installation succeed? how can I fix this problem ? Thanks :)

If everything works you can probably ignore this. The installer is cleaning up some stuff at the end, but it's being a bit overly verbose when trying to wipe a directory that was already gone.

  • Thanks. Also, as I said I followed the manual on installing R packages on the server, however in: ipaddress/ocpu/user/janeDoe/library......it says on the webpage "R package library for user data not found." Why is this? how can I fix it to write R web apps? – swirlydino Jun 27 '17 at 16:30
  • Does `janeDoe` have a home R package library ? If you are root, packages just get installed to `/ocpu/library/` – Jeroen Ooms Jun 27 '17 at 16:40
  • I installed packages using "sudo i R" in (~) directory. So you are saying to do that in the (/janeDoe) directory? how can i make janeDoe have a home R package? – swirlydino Jun 27 '17 at 16:53
  • If you start R as regular user without sudo, it will automatically install packages at the appropriate location in your home dir. – Jeroen Ooms Jun 27 '17 at 17:56
