[Clusterusers] problem running lein/clojure jobs on fly

Hmm, still getting same error, I think, below.
However, I now realize that I've been running my own lein script, in my ~/bin/
So presumably you updated something else, which may not even have had a problem!
However, disabling (renaming) my script, lein gives me a file not found error.
Where is the system-wide lein?
Thanks,

This could be due to a typo in :dependencies or network issues.
If you are behind a proxy, try setting the 'http_proxy' environment variable.
[lspector at compute-1-1 clojush-launcher]$ lein upgrade
The script at /home/lspector/bin/lein will be upgraded to the latest stable version.

It's possible your HTTP client's certificate store does not have the
correct certificate authority needed. This is often caused by an
out-of-date version of libssl. It's also possible that you're behind a
firewall and haven't set HTTP_PROXY and HTTPS_PROXY.
