Hey @Helion55 thanks for opening this PR! we will have a look during the following days, in nebari we use pre-commit to lint the files and commit changes; its just a few typos, but if you want then to be self-fixed, you can pip install pre-commit and run pre-commit install that should then run in your next commit. For now, this is the line that currently needs changes:

error: `statis` should be `stasis`, `status`
  --> docker/scripts/install-conda-environment.sh:56:29

Hey, @ Helion55, I am giving you a heads-up on the review status. We are finishing the latest release of Nebari. Once that's out,, we will include this PR on our discussion board next week. Once again, thanks for opening the PR!
