sudo checks the ownership of its timestamp directory /var/run/sudo by default. what is the ownership of this directry?

Please run as root:

touch /var/test

If you get the same error, probably you had a problem with your disk storage that caused the file system to go to read only mode.

This problem occurs frequently on Vmware VM installations and sometimes on SAN boot configurations.
