Comment 1 for bug 2003294

Hi,

Based on the error you've supplied, issue is not in serial but that wheels are not being build. This means, that for each virtualenv in your environemnt that is being upgraded packages are being cloned independently from external resources, rather then being built once and then installed from repo container, which won't require independant external clonning for each node.

The the issue that should be investigated instead, is why wheels are not build for your environment as they supposed to. From the output it seems, that build target is found properly.

I assume you're having metal deployment? On Wallaby we have obsolete/weird logic that might not work for metal deployments, where we assume that repo host can't be the same as build host.

So for metal deployments before Yoga I'd suggest defining following in user_variables.yml to eliminate that logic drawback:

venv_wheel_build_enable: true

Since Yoga we have changed logic quite dramatically, but it can't be backported due to complexity.
