Python version 3.10.1 from the edge branch changes the directory of Python packages, which causes the following error while trying to install streamlink 3.0.3:

This is related to pip missing, owing to the dir change caused by the new Python version.

One solution is to always force Python and related packages upgrade (python3_upgrade) during the container initialization, instead of conditional upgrade.

Will test this alternative today.

if anyone continues to have this issue, just recreate the container with the updated streamlink installation script (/tools/docker/streamlink_for_tvh_container.sh).
