No write permissions on Google Cloud VM Instance

This might be a long shot, but not sure where else to turn.

But I had my fastai instance running following the fastai guide until a few months ago when I took a pause. Now I get this error using my primary account jupyter@fastai-v3-instance:

  path: /opt/anaconda3/pkgs/cache/d77296e0.json
  uid: 1000
  gid: 1001

If you feel that permissions on this path are set incorrectly, you can manually
change them by executing

  $ sudo chown 1000:1001 /opt/anaconda3/pkgs/cache/d77296e0.json

In general, it's not advisable to use 'sudo conda'.

This problem goes away if I log in on another user e.g. jupyter2@fastai-v3-instance but I get other problems. Can anyone tell me how to give full write permissions to the first account? Not sure how I lost it in the first place.
