I downloaded an open source software from the Internet to emulate white board on my computer. The link is here:
The download was as .zip file with .deb file inside (which I presume is the installation file)

I navigated to the directory where the .deb file is and I used the command:

dpkg -i {filename.deb}  

However, the log says that there are some unmet dependencies. The icon of OpenSankure does show up Dash but when I open Software Center, it says that the software catalog is broken and needs to be repaired.
After repair, OpenSankure disappears from Dash.

Can someone tell me how i can ensure that all dependencies are met at the time of install ?

Selecting previously unselected package open-sankore:i386.

Did you install the 32bit version on a 64bit Ubuntu? I've just installed the 64bit on 64bit and it worked fine. – Oli Oct 2 '13 at 11:47
@Oli I have 32 bit version and tried to install 32 bit version of OpenSankure – Little Child Oct 2 '13 at 13:04

To be sure that all the dependencies of a software will be met, you should install it using the Ubuntu Software Centre or apt-get. However, I understand that sometimes you need to download software from other sources. In that case sometimes dependencies are not met. To fix this, download a graphical .deb installer called GDebi. It will download all the necessary dependencies, if any, at the time of installtion.

Didnt work. Still says it needs some libpaper1 – Little Child Oct 2 '13 at 13:18
Download Synaptic Package Manager. Then search for and install libpaper1. If libpaper1 depends on other softwares, Synaptic will ask you to download them too. Personally I like Synaptic better than Ubuntu Software Centre. It's easier to find the software you're looking for. You can even make a script in Synaptic, so that you can download a software (and its dependencies) to another computer and bring them back to yours. – user152748 Oct 2 '13 at 14:54
So if I have synaptic, GDebi is useless. I can uninstall it ? – Little Child Oct 2 '13 at 16:25
Ya, sure. You can uninstall GDebi. – user152748 Oct 3 '13 at 5:46

Try with:

sudo apt-get install -f

After these dependecies are fixed, try with

sudo dpkg -i {filename.deb}

The first command (apt-get …) should be enough to resolve missing dependencies and configure unconfigured packages. The second command will just re-install the package. If any, the commands should be issued in reverse order. – David Foerster Dec 2 '14 at 12:34
