What does this error message mean?

[jacatone]

Been trying to install the Baghira theme using APT but I keep getting the following error message:

Could not resolve 'us.archive.ubuntu.com'

I tried downloading this archive but no go. How do I fix this? Thanks.

Re: What does this error message mean?

It sounds like a "sources.list" problem. Have you tried:

sudo apt-get update

and then install the application?

If this does not work, you could post your sources.list here. It is located here: /etc/apt/sources.list
