I want to install a .deb file. After going through various questions, I came across these three options: dpkg, GDebi and Ubuntu Software Center. However, I want to install the. Deb file via Synaptic Package Manager only. Is there any method by which I can install. Deb file as well as all it's dependencies via Synaptic Package Manager?

Is there any particular reason why you must use Synaptic? Anything installed on your system will still show in Synaptic no matter what method of installation was used. – matt davis Aug 24 '12 at 13:42
Yes, he wants dependencies to be installed (USC does that; dpkg and gdebit do not). Is there a reason why not using USC (this IS basically the same as using synaptic but with a frontend) – Rinzwind Aug 24 '12 at 13:50
Well that's a personal opinion of not using USC!I won't debate over USC vs Synaptic but one thing that goes against USC(atleast in my case) is that I cann't change the proxy settings of my network,which Synaptic allows me to do. – IgnitE Aug 24 '12 at 13:53
Like anyone else: if you want that software either use USC or you need to install all dependencies yourself when using dpkg. Nothing else in between :+ – Rinzwind Aug 24 '12 at 13:59
I don't know guys. I use gdebi-gtk all the time and it installs dependencies for me. The only time it doesn't is if the necessary dependency is not in the repos. – matt davis Aug 24 '12 at 14:01

Well actually you can't install .deb files through Synaptic.

Is there any reference to your statement,where I can read about it more? – IgnitE Aug 24 '12 at 13:49
my reference: man apt-get – zuberuber Aug 24 '12 at 13:52

You have to install it by command-line:

sudo dpkg -i filename.deb

Command-line is faster and easier as you can know the problem (if there is any) by the debugging information it provides.

dpkg does not resolve dependencies,as was mentioned in earlier comments. – IgnitE Sep 5 '12 at 10:27
