PEAR Succeeded but it is not a valid package archive

Recently I encounter following problem while installing PEAR in Ubuntu 14.04 server, after long search I found that, it is a bug already reported a long before. Solution at bottom of the page.

Solution: Edit /usr/share/php/Archive/Tar.php find and replace the following 'gzopen' with gzopen64' and 'gzseek' with gzseek64'
