I have a docker installation of erpnext using this:
My current installation has v13.6.0. Now I tried to upgrade to v13.19.0.
When I do so I get error 503 with the message: “The system is being updated. Please refresh again after a few moments.”
When I open the console tools in Chrome I found messages like this:
“Failed to load resource: the server responded with a status of 503 ()”
which refer to some “/website_script.js”.
I have also tried to setup a new site and export/import the existing mysql database but with same result.
What is the correct way of upgrading for a docker installation?
