hi, is there any known issue with really long (1,5 h) env preparation after running "pulumi new" on WSL for "azure-python" template? n=1, I haven't tested this on any other PC

Not that I've heard of, "new" is pretty much a git clone and pip install but you could try with "--generate-only" to skip the pip part and see if it's still slow.

yep, you were right. it seems that pulumi-azure-native installation takes quite long. easy to mitigate this by installing it once, globally
