    Browser - google browser,
    OS version - OS: Debian GNU/Linux, v10,
    npm version - 6.14.6

  • What errors or information do you see in the console?
    *I set up a ghost instance in docker container by pulling ghost image from docker registry Docker Hub. The current ghost version is 3.38.2 and ghost-CLI version is 1.14.1. I want to upgrade Ghost to latest version.

  • What steps could someone else take to reproduce the issue you’re having?
    First I tried to update ghost-cli by doing npm install -g ghost-cli@latest but I get this error, "…] / rollbackFailedOptional: verb npm-session 14aa98fa706e539e"
    My idea was to upgrade ghost-cli then do a ghost update to update ghost in the docker container. Please advise what could be the issue here or is there any other way of upgrading Ghost in docker container.
