Weird, I cannot replicate it:

/root/.local/share/uv/python is the wrong path. It should be /opt/homeassistant/.local/share/uv/python, following the home directory of the homeassistant user, which has been explicitly set before, as can be seen in your logs.

Can you open a subshell from the error handler and run some test commands:

runuser -u homeassistant -- whoami
runuser -u homeassistant -- env | grep -E '^HOME|^UV_'
runuser -u homeassistant -- uv python dir

[btuerk89]

Thanks for your help.

What I did:

1. Create manual backup
2. Restart RPI and wait until everything is fine again
3. Started reinstall, ran into same problem as before and opended a subshell

Output:

### same as above ###
[FAILED] DietPi-Software | Installing Python
 - Command: runuser -u homeassistant -- uv python install -U 3.14
root@DietPi:/opt/homeassistant# runuser -u homeassistant -- whoami
homeassistant
root@DietPi:/opt/homeassistant# runuser -u homeassistant -- env | grep -E '^HOME|^UV_'
HOME=/opt/homeassistant
root@DietPi:/opt/homeassistant# runuser -u homeassistant -- uv python dir
/root/.local/share/uv/python

After exiting everything HA is not running anymore so I restored my backup.

Side note:
Tried again your commands in the terminal and output is different:

root@DietPi:/# runuser -u homeassistant -- whoami
homeassistant
root@DietPi:/# runuser -u homeassistant -- env | grep -E '^HOME|^UV_'
HOME=/home/homeassistant
root@DietPi:/# runuser -u homeassistant -- uv python dir
runuser: failed to execute uv: Datei oder Verzeichnis nicht gefunden

[MichaIng]

Can you install uv separately and rerun the last command?

dietpi-software install 217

And one more time with sudo to start a clean environment:

runuser -u homeassistant -- uv python dir
sudo -u homeassistant -- uv python dir

[btuerk89]

Installation of uv was fine I think.

Now output is:

root@DietPi:/# runuser -u homeassistant -- uv python dir
/root/.local/share/uv/python
root@DietPi:/# sudo -u homeassistant -- uv python dir
/home/homeassistant/.local/share/uv/python

Maybe it has some effect: I am using LXTerminal within LXDE desktop environment and autostart option 2

[MichaIng]

So it is something about the shell environment, indeed. Can you show the full output of:

env

But please mask private/sensitive values, if present.

Found it:

root@VM-Trixie:/# runuser -u homeassistant -- uv python dir
/opt/homeassistant/.local/share/uv/python
root@VM-Trixie:/# export XDG_DATA_HOME=/root/.local/share
root@VM-Trixie:/# runuser -u homeassistant -- uv python dir
/root/.local/share/uv/python

Probably a good reason to switch from runuser to sudo, and pass only those variables we really need.

[btuerk89]

Great, good to hear.

Anything else I can do?

Since my system is running fine so far I will wait for v10.4 and try it again later.

[MichaIng]

You can test it via dev branch now:

G_DEV_BRANCH dev
dietpi-software reinstall 157

And to go back to master/stable branch with next release:

G_CONFIG_INJECT 'DEV_GITBRANCH=' 'DEV_GITBRANCH=master' /boot/dietpi.txt
