Mostly for Josiah, but sending to the list in case anyone else has insights.<br>
<br>
Trying to run Clojure (via leiningen) on Fly for the first time in months, and getting errors.<br>
<br>
This feels familiar, but I can't seem to find a past thread in which it was raised/addressed.<br>
<br>
If I ssh to a node and cd into a Clojush directory and try to run a demo I get:<br>
<br>
[lspector@compute-1-1 clojush-launcher]$ lein run clojush.problems.demos.simple-regression<br>
Could not transfer artifact com.lowagie:itext:pom:2.1.7 from/to central (<a href="https://repo1.maven.org/maven2/" rel="noreferrer" target="_blank">https://repo1.maven.org/maven2/</a>): Received fatal alert: protocol_version<br>
Could not transfer artifact org.apache.xmlgraphics:batik-svggen:pom:1.8 from/to central (<a href="https://repo1.maven.org/maven2/" rel="noreferrer" target="_blank">https://repo1.maven.org/maven2/</a>): Received fatal alert: protocol_version<br>

This could be due to a typo in :dependencies or network issues.<br>
If you are behind a proxy, try setting the 'http_proxy' environment variable.<br>
<br>
Thinking that maybe I needed to upgrade leiningen I tried but got this:<br>
<br>
[lspector@compute-1-1 clojush-launcher]$ lein upgrade<br>
The script at /home/lspector/bin/lein will be upgraded to the latest stable version.<br>
Do you want to continue [Y/n]? Y<br>

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out-of-date version of libssl.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