I ran dpkg command and it worked like a charm.
Until now, I have not found it necessary to install software according to my
wishes. But, I thought that it would be good to have control on software
installation rather than ubuntu doing it for me. Once I get more familiar with
linux aura, I might play with the settings, just for the sake of fun...lol
I was thinking of installing a simulation software and therefore, I might need
to install the software in a specifc directory. So, if I would need that, then I
will start searching on the internet for more understanding and post questions
again.
