python / autocompletion layers: anaconda auto-install failure keeps blocking python files editing

[deb0ch]

Description

When using python and autocompletion layers out-of-the-box, anaconda automatic install fails and keeps showing errors when editing python files.

The bug does not appear when you just installed the python layer, only after restarting emacs.

This makes python mode unusable as the error popups keep coming back.

Reproduction guide 🪲

• Start Emacs with a python buffer
• install python layer when prompted
• restart emacs

Observed behaviour: 👀 💔

• error popup window keeps showing, even after closing it

Expected behaviour: ❤️ 😄

• error popup window should appear only once
• in a wonderful world there should be no errors at all

Looks like the linked upstream issue is fixed, so closing this one. If it still occurs, let us know.
