Linux Decompression Error

When installing the JDK on Ubuntu, you always encounter errors during the decompression process.

First wget command download file: $wget-C http://download.oracle.com/otn-pub/java/jdk/8u40-b26/jdk-8u40-linux-x64.tar.gz

Prompt download success, the next decompression;

Decompression: $tar-ZXVF jdk-8u40-linux-x64.tar.gz

Always follow the following error message after execution:

Gzip:stdin:not in gzip format
Tar:child returned status 1
Tar:error isn't recoverable:exiting now

Check a lot, some solutions are: $tar-xvf remove Z.

Some say first to confirm whether the file is a zip type: $file jdk-8u40-linux-x64.tar.gz

jdk-8u40-linux-x64.tar.gz:html document, ASCII text, with very long lines, and CRLF line terminators

See the return information, it dawned, is actually an HTML page. So the root cause of the error is this.
