I'm getting this in babashka. It seems spire has the same problem: https://circleci.com/gh/epiccastle/spire/627?utm_campaign=vcs-integration-link&utm_medium=referral&utm_source=github-build-link so it might be a general Mac image problem?

my linux box lein upgrade is ok

do you want to try on your mac @borkdude

(if its ok on your mac then theory: could be http download. Could be a transparent http proxy in circleci infra with corrupted file??)

@retrogradeorbit @marc-omorain fixed by pinning lein to the previous version:

#!/usr/bin/env bash

curl  > lein
sudo mkdir -p /usr/local/bin/
sudo mv lein /usr/local/bin/lein
sudo chmod a+x /usr/local/bin/lein
