Issue to install add-on

[JeromeH27]

Hello,

I got this error during the installation:
Failed to install add-on
The command '/bin/ash -o pipefail -c apk --update --no-cache add python3 py3-pip && pip install --no-cache-dir requests flask' returned a non-zero code: 2

my current configuration is:
Core 2024.12.5
Supervisor 2024.12.0
Operating System 14.1
Frontend 20241127.8

Do you know how I can fix it?

Regards,
JeromeH27

Hi @JeromeH27 - sorry for the delayed response. Holidays. 😄

Can you share your platform? Are you running Home Assistant on a PC, NAS, Pi, etc.?

[JeromeH27]

Hi ChrisRomp,

no issue :o)

Home Assistant is running on a laptop, here some informations:
OS Version: Home Assistant OS 14.1
Home Assistant Core: 2025.1.0

feel free if you need more details.

[ChrisRomp]

What CPU? I'll see if I can reproduce your issue.

[ChrisRomp]

And what OS is your host machine?

[JeromeH27]

OS is Home Assistant OS 14.1, it seems to be based on Alpine Linux 3.21

CPU is a intel x86-64

[ChrisRomp]

Alright, I've managed to repro this. The important bit was above the error code in the log:

error: externally-managed-environment

× This environment is externally managed
╰─>
    The system-wide python installation should be maintained using the system
    package manager (apk) only.

    If the package in question is not packaged already (and hence installable via
    "apk add py3-somepackage"), please consider installing it inside a virtual
    environment, e.g.:

    python3 -m venv /path/to/venv
    . /path/to/venv/bin/activate
    pip install mypackage

    To exit the virtual environment, run:

    deactivate

    The virtual environment is not deleted, and can be re-entered by re-sourcing
    the activate file.

    To automatically manage virtual environments, consider using pipx (from the
    pipx package).

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.
The command '/bin/sh -c apk --update --no-cache add python3 py3-pip   && pip install --no-cache-dir requests flask' returned a non-zero code: 1

It looks like this error: externally-managed-environment thing coming from PEP-0668 is relatively new (or newly enforced).

It looks like we can clobber this with the --break-system-packages arg, which I'm ok doing in a container since that (should) control the blast radius sufficiently.

I'll do some tests and push an update.

[ChrisRomp]

@JeromeH27 Pull the updated version v1.1.0 in your HA and try the installation again.

[JeromeH27]

thank to have tried to fix it.

I just do a try, I got a similar error:
The command '/bin/ash -o pipefail -c apk --update --no-cache add python3 py3-pip' returned a non-zero code: 2

[ChrisRomp]

I'm gonna need more of the log if you can get it (check supervisor logs), and make sure you're pulling/building v1.1.0.

[ChrisRomp]

In fact I can tell from that command that it's not the updated one. It's missing the new args.

[ChrisRomp]

Oh wait that's failing on the apk command not the pip command. Ok... try and get me more logs and that'll help. Otherwise I have no idea.

[JeromeH27]

I confirm the try is with version 1.1.0.

I just redo a try, here the logs from supervisor:
