How to fix couchdb install, erlang

[polklabs]

While updating couchdb on Ubuntu through 'apt --upgrade' it asked to enter a Erlang cookie, I entered a value similar to the placeholder value. Now couchdb.service will not start.
When checking the logs I see

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
  Monster detected ohno!, aborting startup.
  Please change the Erlang cookie in vm.args to the same
  securely generated random value on all nodes of this cluster.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The issue is I'm not running a cluster. Just a single couchdb instance.

How can I update this cookie / remove it / get the single couchdb node working again?

Found the solution.
For anyone else with this issue: Had to change '-setcookie xxxx' in the file /opt/couchdb/etc/vm.args
The prompt in the update did not actually set this value
