[EDIT]: Here is how to do it:

Find the download link and wget it. If your downloading from Oracle they make you accept the licence agreement, and then give you the link. If you get a certificate error, add the no-check-certificate option to wget.

If you want the Oracle JDK8 for ARM, issue this statement:

wget http://www.java.net/download/jdk8/archive/b99/binaries/jdk-8-ea-b99-linux-arm-vfp-hflt-17_jul_2013.tar.gz --no-check-certificate


I am attempting to download the JDK8 for Linux ARM (218.45MB file) from https://jdk8.java.net/download.html .

If I accept Oracle's agreement and get the link, I try this in WGET:

wget http://www.java.net/download/jdk8/archive/b99/binaries/jdk-8-ea-b99-linux-arm-vfp-hflt-17_jul_2013.tar.gz

and receive the following error:

Connecting to www.java.net (www.java.net)||:443... connected.
ERROR: The certificate of `www.java.net' is not trusted.
ERROR: The certificate of `www.java.net' hasn't got a known issuer.

The first time I tried to download it, it actually got about 99% of the way through before Midori crashed. The MD5 didn't match.

Now every time I try it appears to be getting worse, now its crashing at less than a third of the way there. I've tried about 10 times.

Even when I initially got my RPi and had no programs running, Midori seemed to crash a lot.

How can I get around this?

With Midori open, my free -h says 16M free in memory, 31M free in buffers/cache. With Midori closed, my free -h says 7M in memory, 114M in buffers/cache.

  • Try adding --no-check-certificate to the wget command; My pi can download it.

I have no idea why Midori has as much trouble as it does, but I managed to grab the url for you:

  • Hey @Jacobm001, I tried that route earlier with wget and I receive the error listed in my edit above. Do you know a way around that? Thanks Jul 19, 2013 at 22:51
  • Try adding: --no-check-certificate
