Ubuntu OpenVPN – resolvconf: Error: /etc/resolv.conf must be a symlink
by Riley MacDonald, June 14, 2017

After installing some updates my OpenVPN client was suddenly unable to resolve any host names. The following output was observed when attempting to connect:

Warning: resolvconf: Error: /etc/resolv.conf must be a symlink

Examining /etc/resolv.conf indicated the file was not being updated as expected. One of the updates must have broken the symlink/configuration. I was able to resolve the issue by running:

$ dpkg-reconfigure resolvconf

Executing this command runs a reconfiguration script which backs up the original /etc/resolv.conf file and creates a new dynamic symlink resolving this issue.
