Hi again,
hmmm, ok then. Can you try force upgrade again, as per the solution in this post: Error Docker - Manage Images - List index out of range?
*Caution: Please be aware if this is a production environment, I am just trying to help here, not trying to cause further issues.
Sorry for keeping asking simple questions and thanks for answering to all of them but there is no other way of investigating.
Edit: @reasecret Is the Cyberpanel /.git file in the directory specified in the 12-02-18 error or is it missing?
