It's kinds show stopper to me. Any suggestion how to fix > this quite annoying bug? This is not really a bug per-se, and this behaviour has existed since at least July 2014, with commit 95a572282e (pkg-infra: move the git download helper to a script), since then the git download is done with the extra environment defined in EXTRA_ENV, and namely: EXTRA_ENV = PATH=$(BR_PATH) [....] and where: BR_PATH = "$(HOST_DIR)/bin:$(HOST_DIR)/sbin:$(PATH)" So, this is not a new behaviour in 2021.02, but most probably you previously did not have host-python3 built as part of your configuraiton, and now it is. And then, it takes precendence over the system python3. I don't see a easy way around, though... But without the actual error you are seeing, it is impossible to suggest further tracks of investigation: is the missing stuff a built-in module of python, or is it a external one? Regards, Yann E.
