I would also like to add that you're trying to download (and I presume, install) an ancient version of the JRE, which has numerous serious, exploitable security vulnerabilities that will never be patched.

The best possible outcome is that you will have an obsolete and insecure Java running on an obsolete and insecure Ubuntu.

Here are the official instructions to install a supported Java on a supported Ubuntu release: https://help.ubuntu.com/community/Java
