[BUG] HACS custom component can no longer install dependencies

[3ll3d00d]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Using the latest image with HACS 2.0.1 installed, dependencies of custom integrations fail to install due to OS permission errors

Expected Behavior

dependency should install normally

Steps To Reproduce

• add some new custom integration with a dependency (e.g. lghorizon, ukbincollectiondata)
• restart
• dependency cannot be installed due to permission errors

I'm not sure when this started happening as it's been a while since I added a new component

one obvious difference is that the above logs show packages attempting to be installed into system python (/usr/local/lib/python3.12/site-packages) whereas I can see that previous dependencies went into config/.local/lib/python3.12/site-packages

It's due to upstream switching to uv instead of pip.

Pip installs packages in the user's home folder when it's run by a non-root user. But uv doesn't support that behavior astral-sh/uv#2077

So we either fix the permissions of the system folders so abc user can install there, or we create a venv in the config folder. Both have their downsides and we tried both options in the past and ran into issues. I'll have to do some testing to see if some things changed.

For now, you can manually install the package via docker exec homeassistant pip install packagename==version and it should persist through reboots and recreation.
