Does not install

Poetry installed with brew install poetry. This is why core functionality should not be in a plugin.

Poetry installed with brew install poetry

https://python-poetry.org/docs/#installation

if you have a problem with homebrew installation, you'll need to take that up with homebrew

Because poetry-project-instance depends on python-apt (3.0.0) which doesn't match any versions, version solving failed.

bundling unrelated problems into a single issue report is not helpful

• those who are installing via homebrew should instead use a supported method, or report their issue to homebrew
• those who are seeing requirements such as python-apt and ufw should know that these do not come from poetry or this plugin
  • you will likely have to figure out for yourselves what is introducing them, and report the issue there (wherever that is)
