Update from Ubuntu stock OpenSSL 1.0.1f to 1.0.2d manually

After getting install ubuntu onto a newly formatted notebook, then found out that the stock OpenSSL version is out of date. After some unsuccessful attempt and finally fond a reference from website : http://askubuntu.com/questions/429385/upgrade-openssl-on-ubuntu-12-04 stated:

First you need to completely remove the old installation: (this will break most systems! Be careful! Most people will regret this) apt-get purge openssl

sudo apt-get purge openssl

You may want to clean house by running:

apt-get autoremove && apt-get autoclean

Then you should download and compile the version you want (full list)

wget https://www.openssl.org/source/openssl-1.0.2d.tar.gz

and it saved in ~/home directory.

get into the directory where gz file is then

Un-gz the file

$ gzip -d openssl-1.0.2d.tar.gz

To unpack a tar file, type

tar -xvf openssl-1.0.2d.tar




Then after unpack it, cd into the openssl-1.0.2d directory the

cd openssl-1.0.2d

./config --prefix=/usr/

make

sudo make install







The key is in this line. It remove the local installed list (sync) from auto update server of openssl. 

apt-get autoremove && apt-get autoclean

If it not this line, after install it would still show 1.0.1f version.
