gzip: stdin: not in gzip format tar: Child returned status 1 tar: Error is not recoverable: exiting now
This means the file isn't really a gzipped tar file -- or any kind of gzipped file -- in spite of being named like one.
When you download a file with wget, check for indications like Length: unspecified [text/html] which shows it is plain text (text) and that it is intended to be interpreted as html. Check the wget output below -
[root@XXXXX opt]# wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/8u144-b01/090f390dda5b47b9b721c7dfaa008135/jdk-8u144-linux-x64.tar.gz"--2017-10-12 12:39:40-- http://download.oracle.com/otn-pub/java/jdk/8u144-b01/090f390dda5b47b9b721c7dfaa008135/jdk-8u144-linux-x64.tar.gzResolving download.oracle.com (download.oracle.com)... 23.72.136.27, 23.72.136.67Connecting to download.oracle.com (download.oracle.com)|23.72.136.27|:80... connected.HTTP request sent, awaiting response... 302 Not AllowedLocation: http://XXXX/FAQs/URLFiltering/ProxyWarning.html [following]--2017-10-12 12:39:40-- http://XXXX/FAQs/URLFiltering/ProxyWarning.htmlResolving XXXX (XXXXX)...

For a correct file, the wget output will show something like Length: 185515842 (177M) [application/x-gzip] as shown in the below output -

You can also file, head, less, view utilities to check the file. For example a HTML file would give below output -
[root@XXXXXX opt]# head jdk-8u144-linux-x64.tar.gz<!doctype html><html lang="en"><head> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link href="/css/print.css" rel="stylesheet" media="print"> <link href="/css/main.css" rel="stylesheet" media="screen"> <link href="/css/font-awesome.min.css" rel="stylesheet">The above shows it is indeed an HTML page which we are trying to unzip/untar - something that won't work. If it was indeed a correct zip file (binary in nature) the output of head would have produced garbage - something like below -

Also check your proxy settings and make sure you have the right proxies enabled to download/wget it from the correct source.
Hope this helps.
Just click first on that link and go to HTML page where actual downloads or mirrors are.
Its really misleading to have full link which ends in .tgz when it actually leads to HTML page where real download links are.I had this problem downloading Apache Spark and wget-ing it into Ubuntu.
