Obgos,
For some reason your computer (or perhaps just the terminal) does not
have have access to the internet. This is not an R related issue, but a
hardware or Ubuntu related one.
I suggest you speak to your system administrator or visit the Ubuntu
forums for help. R-sig-Debian is only for R related issues.
