It seems that you are trying to install a application in tar.gz format from source-code with apt-get?

This type format is not installed with apt-get.

To install applications in the tar.gz format refer to Compiling Easy How To at -

I'm asking because your changing into a folder on your desktop called SYNTENYMINER which is probably the extracted tar.gz – Auge Jul 17 '12 at 8:42

The above information says that, you tried to install syntenyminer from repository with apt-get install syntenyminer which does not exist in repo. Thats why terminal give you

E: Unable to locate package SYNTENMINER

this output.

At last you tried to edit sources.list file with gedit. It open blank because, there is no such file in your given address. You gave etc/apt/sources.list which does not really exist. The correct path of the sources.list is /etc/apt/sources.list Then the command will be like this sudo gedit /etc/apt/sources.list

If you don't provide the actual name of the package the apt-get can not install your software.
