Ubuntu – apt-get install doesn’t get the package

You can use non-standard packages in Ubuntu. You have to take care of the dependency resolution yourself.

You can download the package from the link in your questions.http://packages.ubuntu.com/karmic/libapache2-mod-wsgi

After you download, you can install with sudo dpkg -i or gdebi the gui .deb installer.

You may have to download additional a packages to resolve dependencies.

The problem is that apt/dpkg can't look inside the image files for the .deb package files. You need to get the .deb files themselves to your USB source.

I would do this as follows:

1. Install Ubuntu server on another computer (or into an empty partition or into a virtual machine) that does have a network connection.
2. Run 'aptitude clean' to clear out the package directory at /var/cache/apt/archives
3. Run 'aptitude install xfce'
4. /var/cache/apt/archives will now have the .debs you need. Copy these over to your drive and run the install on the original computer.

There's also a program called apt-offline that that handles this kind of situation but probablly not worth learning for just one install.
