ERROR - DVR:Grabber: No write permission

In the latest build (Version 1.7.2.3878) on Ubuntu 16.04 Server, I’m getting this error whenever I try to record a show.

The libraries are NFS mounted and I have verified that the user can write to the libraries by logging in as ‘plex’ and creating a text file in the library. Any suggestions on how to troubleshoot this?

I have also created a local directory and set permissions to 777 and still am having the issue.

Just an update that it did turn out to be a permissions issue. Even though the account was a member of the group, it appeared that it needed ownership of the directory. :s
