Prefect Community

Hello, I just installed Prefect on ubuntu using this command "pip install prefect" but I couldn't run "prefect version". It said "Unknown setting 'PREFECT_ORION_UI_API_URL'. (type=value_error)"

hi <@U03LE28LW1E> - what does this command show?

```cat ~/.prefect/profiles.toml | grep ORION```
unless you have set `PREFECT_HOME` somewhere else?

this is because `PREFECT_ORION_*` settings are removed from / no longer recognized by the library. they've been replaced by settings like `PREFECT_SERVER_*`

<@U02GMEZU18B> Thanks for guiding me in the right direction. I have got it fixed.
