So I recently installed Ubuntu onto my laptop and have just fallen in love with it. The only problem I'm facing is that whenever I try and install a .deb application (using GDebi package installer,) I get an error status saying "Error: Dependency is not satisfiable: libwxgtk3.0-0 (>= 3.0.0)" What does this mean? Is there a way to fix it?
Edit: The version I'm currently using is "ubuntu 16.04"
Super easy fix. When you're trying to install a package it's easiest to do it through Terminal (in my opinion). If you're trying to install, say, myprogram.deb, you would type into terminal sudo apt-get install myprogram. Sometimes there are other ways (I would suggest using synaptic package manager if possible). If your package exists and you still have a dependency, type into Terminal sudo apt-get install myprogram checkinstall. If you can't find your package, you can install the dependency by hand with sudo apt-get install dependency-goes-here, then try installing your package again.
The version of the missing dependency is the problem. Your app is looking for libwxgtk3.0-0 whereas the one installed on Ubuntu 16.04 is libwxgtk3.0-0v5. The version your app is looking for is not available in the repos.
There are two versions of the package here. The latest one is the one for vivid. You can download and install it manually using gdebi and then you can try installing the app you want.
Before you proceed though, make sure libwxgtk3.0-0v5 is actually installed. If not, install that one first and if you face the same problem again, then try the manual installation.
