@Aditya The resolution of this problem isn't there because the root of the issue is not based on unmet dependencies. –  Lucio Jan 16 '13 at 21:49

As I can see you have problems installing firefox because it is trying to overwrite a directory that is used by adobe-flashplugin. So you need to uninstall this plugin first:

sudo apt-get remove adobe-flashplugin* 

Now install you will be able to install firefox without problems.

sudo apt-get update
sudo apt-get install firefox

For further information related with the problem E: Sub-process /usr/bin/dpkg returned an error code (1) review this question.

that didn't do it –  Deus Deceit Jan 16 '13 at 20:30
    
Yes, I did. I also messed with a lot of stuff. I think I removed everything relevant to it. But still I can't install it again. I get an error when trying to re-install. –  Deus Deceit Jan 16 '13 at 20:51
    
Thanks for trying to help... I bet the comments above don't show much gratitude. Sorry if that's how it seemed. –  Deus Deceit Jan 16 '13 at 21:05

Remove adobe-flashplugin and try again. To remove: sudo apt-get remove adobe-flashplugin* –  Lucio Jan 16 '13 at 21:34

As simple as that... It worked! Add that to your answer if you want. I'll mark it as accepted anyway. –  Deus Deceit Jan 16 '13 at 21:39
