Raspian PI cant upgrade/reinstall past version 6. Help please

Hi Any thoughts I have tried

pip3 install --upgrade homeassistant

Runs ok but stays on v 6.0

I tried

pip3 install homeassistant==0.XX.X (With various version)

Stays on 6

I tried uninstalling and reinstalling - No joy stays on version 6

Any thoughts or help please?

Thanks

I assume you installed HA in a python venv?
So if you not activate the venv before upgrade, a new HA gets installed in the normal raspbian environment.
