Manjaro Linux, Krita 5.1.1

After install docker is empty. If try to "SD check requirements and fix" option, it show this error:

AttributeError

A problem occurred in a Python script. Here is the sequence of
function calls leading up to the error, in the order they occurred.

The above is a description of an error in a Python program. Here is
the original traceback:

The docker stays empty when Defuser can't connect to the WebUI.
Is it possible that either the UI is not running on the default localhost:7860, or it didn't fully launch (i.e. was accessible in a browser as well) before you opened Krita?
You should see this in your WebUI terminal:

Running on local URL:  http://127.0.0.1:7860

To create a public link, set `share=True` in `launch()`.

I will improve this behavior in a future release.

[valden80]

Yes, it's fully launched, I opened link http://127.0.0.1:7860 in browser and generate test image. Then I start Krita and have empty docker and error.

Also I just updated SD to last version by git pull, and added --api option to the webui-user.sh - nothing changes.

Thank you very much for your time and help with fixing this issue.
You shouldn't need the --api argument at all, actually.

I had a bad url string in a GET request somewhere, which meant defuser would only work on a machine with an edited hosts file.

I pushed a new build that hopefully fixes it. Please update and see if defuser starts normally.
If it does not, let me know and i will reopen this.
