Daniel Stenberg,
        I followed your suggestion to fetch the 32 bit libcurl package with OpenSSL support
which runs on a 64 bit Ubuntu Linux 15.10 operating system and I got the installation error:
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe). Please advise how to fix
this error. Thanks.
