This question already has an answer here:

I keep trying to install programs, by simply downloading the program, and clicking on it, but I see things are not that simple. Has anyone come up with a simple way to install different programs, without having to rely on Synaptic or Aptitude?

Example: I tried to install a .deb package. Went to the site, downloaded the package, opened up the command line (after making the file executable), the errors began. First there was a dependency file that was required, then there was a public key that was needed, man can someone make this a little bit simpler for a newbie. I think a newbie spends half of his time searching google to figure out how to make things work on Linux. Someone please help make this more simple? Tanks

Install Gdebi. – Parto Feb 11 '14 at 17:30
sounds like you are looking to install a specific ".deb" which program are you having a problem with? And which version are you using. – Mateo Feb 11 '14 at 17:42
ffmpeg -i video.mp4 -f mp3 -ab 192000 -vn music.mp3 – showmemn Feb 11 '14 at 17:55

To install a .deb package, just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo dpkg -i <package_name>.deb

If you get a dependency error, you can run sudo apt-get install -f to download and install dependencies, otherwise; you'll have to install dependencies on your own.

For a new user, its easier to use synaptic , Ubuntu software Center, or apt to install packages. Take a look at How do I install applications in Ubuntu?

For more info on dpkg, see dpkg Command Cheat Sheet

What about installing other programs like .exe, is that also possible with gdebi? I know the program is for Windows, but is there a way to recompile this? – showmemn Feb 11 '14 at 17:38
Also, what about installing from a URL? – showmemn Feb 11 '14 at 17:39
.exe files are windows based, and can't be installed natively in Ubuntu. The way to use .exe files in Ubuntu is by using Wine. what do you mean installing from a UR? – Mitch Feb 11 '14 at 17:43
I remember seeing something about useing apt-get from the browser windows – showmemn Feb 11 '14 at 17:45
do you mean "apt-links" the "Ubuntu apps directory" gives you an apt link that will open in the software center for example (these usually are only found there because it often confuses users, and makes it hard to download files in other browsers/systems) – Mateo Feb 11 '14 at 17:47

Try to install .deb packages through gdebi,

 sudo gdebi filename.deb

Run the below command to install gdebi,

 sudo apt-get install gdebi

Installing the .deb file through gdebi will remove the dependency errors.

sudo apt-get install gdebi sudo: unable to resolve host srv1 Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: Returned the following error:The following packages have unmet dependencies: gdebi : Depends: gdebi-core (= 0.8.5ubuntu1.1) but it is not going to be installed – showmemn Feb 11 '14 at 17:42
sounds like you broke your system trying to install something else @showmemn – Mateo Feb 11 '14 at 17:43
worked, had to run sudo apt-get install -f – showmemn Feb 11 '14 at 17:44
