First time running "lein repl". Non stop crashing.

Have reinstalled java and re downloaded the script a number of times. A very annoying problem keeping me from working with Clojure. Only downloaded the script and enabled it for running.

Does this issue help?

[adg-adg]

The distro is fully updated as far as I know, so can't simply update nss. Already fully reinstall openjdk-8 to oracle-java8 to no effect. This has been going on for weeks, but I took a break from trying to fix it. What are some dependencies I should check or reinstall and what could be a possible culprit. This whole issue is very perplexing since I have basically not done any work with clojure as of yet. It might be important to add that I have installed an Intellij plugin Cursive for clojure development, but have not done anything other than get lost, possibly due to it not working because leiningen isn't working. Please help with anything, really want to get this sorted out.

[winks]

Trying to reproduce. So far, openjdk-8-jdk-headless seems to work fine:

Also with Oracle's JDK

[adg-adg]

Well it seems identical in that case. What could be an issue at stake here?

axg@isidio:~/bin$ uname -a Linux isidio 4.4.0-28-generic #47-Ubuntu SMP Fri Jun 24 10:09:13 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

and my java version is the same as the one you test. I really appreciate the effort. What could be a possible issue with this? My current Ubuntu install was upgraded from 15.10 to 16.04, maybe there is some discrepancy there. What else could I check, or is my only option reinstalling Ubuntu due to some hidden bug?

a) are you behind a proxy? b) can you try curl -v https://repo1.maven.org/maven2/ c) can you try LEIN_JAVA_OPTS="-Djavax.net.debug=SSL" lein repl

[winks]

Maybe dpkg-reconfigue ca-certificates also helps.

cf: https://github.com/docker-library/openjdk/issues/19

[hypirion]

I've had issues with this on ubuntu before, sometimes the certificates aren't properly setup.

sudo update-ca-certificates -f

seems to usually resolve the issue.

[adg-adg]

curl -v https://repo1.maven.org/maven2/

http://pastebin.com/7YZbnfyg

LEIN_JAVA_OPTS="-Djavax.net.debug=SSL" lein repl

http://pastebin.com/3sUuWS7X

dpkg-reconfigure ca-certificates

http://pastebin.com/2ieDgB6m

sudo update-ca-certificates -f

http://pastebin.com/V2sCEQc6

I have no idea what could be causing this anymore. These commands seemed to execute properly but the issue remains. This is what I continue to get when running a simple lein repl (it hangs on that last line and I terminate with C-c :

Ended up doing a clean reinstall of the system. Thankfully everything is easy and understandable to setup with my linux setup. No problems this time around. Thanks for all the help in trying to find a possible culprit.

[hypirion]

Thanks for being patient :) If you end up with this issue again, feel free to reopen.

[maw87]

Had the same issue, using Ubuntu 15.10, Java 1.8 and 4.2.0-42, fixed it by updating the certs with "sudo update-ca-certificates -f". Thanks for the tip.

[z0del]

Same issue on my Calculate Linux (Gentoo)

[xueluofeng]

Maybe dpkg-reconfigue ca-certificates also helps.
