@bukzor and I was able to debug this error, its basically the shebang being too long, due to a jenkins job name. I was trying to run the venv-update inside a path that was >127 character long.

@bukzor requested me to file a ticket to update/patch venv-update to fail hard in this case so that its at least a bit more obiv in the future what happened.

@bukzor +1, wasted an hour on this today
