It looks like the old update instructions I found are out of date. I’ve been following the instructions here with some success. I removed a ton of junk files from my ghost directory.

Next I ran ghost doctor and was told I had some permission issues and that I should run sudo find ./ ! -path "./versions/*" -type f -exec chmod 664 {} \; so I did. Then I was able to run ghost update successfully, and now I have:

Ghost-CLI version: 1.15.3
Ghost version: 3.40.1 (at /var/www/ghost)

However, I’m now getting the following error when running ghost start:

✖ Starting Ghost: morgz-org
A ProcessError occurred.

Message: EACCES: permission denied, open '/var/www/ghost/config.production.json'
Exit code: EACCES


Debug Information:
    OS: Ubuntu, v18.04.4 LTS
    Node Version: v12.20.0
    Ghost Version: 3.40.1
    Ghost-CLI Version: 1.15.3
    Environment: production
    Command: 'ghost start'

The permissions for config.production.json are:
-rw-rw-r-- 1 ghost ghost 798 Jun 24 21:01 config.production.json

The only thing I see that might be an issue is that I’m logged in a ghost-mgr, but the owner of the file is ghost?
