With all things being constant, I suddenly started getting this error when trying to update wordpress via the control panel. It was working perfectly a few weeks ago and I haven't made any changes. I have the right file permissions.
Was there changes to the network or increase in security of some sort?
Thanks
Thats what puzzled me, no system changes were made since the last auto update, which was about two weeks ago.

That error is most likely caused by an issue with file permissions. There isn't anything on the DigitalOcean end that would have led to it. Could you check to make sure something didn't change on your system? What's the output of
ls -la -Rin yourwp-contentdirectory?
