📝 Provide a clear and concise description of the issue.

I am not an expert on this. I tried to some things with the help of Claude. I also do not know if it is for my installation only, but i thought I report it anyway. Please dismiss the issues if applicable. Thank you.

Issue:
After running update in the Immich LXC console, both immich-web and immich-ml services fail to start. The root cause seems to be that the ml-venv Python virtual environment is not created during the update because the sudo --preserve-env invocation in update_script() fails silently with Invalid argument on this LXC setup.

🔄 Steps to reproduce the issue.

1. Install Immich using the community-scripts helper
2. Run update in the LXC console
3. Update reports success
4. Immich is unreachable — 502 Bad Gateway
5. systemctl status immich-ml shows exit-code failure
6. Running bash /opt/immich/app/machine-learning/ml_start.sh reveals: /opt/immich/app/machine-learning/ml-venv/bin/activate: No such file or directory

❌ Paste the full error output (if available).

sudo: unable to set runas group vector: Invalid argument
sudo: uv: Invalid argument

/opt/immich/app/machine-learning/ml_start.sh: line 4:
/opt/immich/app/machine-learning/ml-venv/bin/activate: No such file or directory

ModuleNotFoundError: No module named 'gunicorn'

🖼️ Additional context (optional).

Manually recreate the venv after a failed update:

bashcd /opt/immich/source/machine-learning
su -s /bin/bash immich -c "VIRTUAL_ENV=/opt/immich/app/machine-learning/ml-venv uv sync --extra cpu --active -n -p python3.11 --managed-python"
systemctl reset-failed immich-ml && systemctl start immich-ml

Possible fix:
Fall back to su -s /bin/bash immich -c "..." if the sudo --preserve-env invocation fails, or add error checking so the update does not report success when the venv creation step fails.

From which Version ?

Your whole LXC is broken, uv is missing, venv is missing, ml is broken.

Immich is pinned to a specific stable release for a reason so steps 1 and 2 make no sense, please stop using AI to try and brute force through a safety block in the script and complain script is broken as it's not.

Ok fair enough. I tried not to be to quick to ask and try myself first with all the help I could get. I think i understand now that it is on my side. My sincere apologies for that. Case closed.
