HOWTO: apt-offline ?

[Bdfy]

I want install packages from Ubuntu's repositories but my computer have not internet
Can I know depends for this package ( in my current system ) and download its manually in not debian system ?

You can find the dependencies for a package with apt-cache showpkg (or synaptic).
One way of installing the packages without a direct connection would be to download them from the repository using a web broswer or something, copy them over to your Ubuntu machine, and install them with
sudo dpkg -i package files... .

There're other ways - have a look at
this part of the APT HOWTO (http://www.debian.org/doc/manuals/apt-howto/ch-basico.en.html#s-dpkg-scanpackages)

and the apt-offline package.
