$apt-get install glade3-3.0.1.tar.gz
the message that terminal displaying is:
Reading Package Lists... Done
Building Dependency Tree... Done
E: Couldn't find package glade3-3.0.1.tar.gz.
----
in my file system,
/etc/apt/sources.list containes only debian CD name and one website.
what i have to do to install that softwere.
my destro is debian 3.1.
any help will be appreciated.

"apt-get install glade" will install glade from the Debian repo.

tar.gz packages only contain source code (and can't be installed with apt).
