I have Windows 7 as host system, and installed Ubuntu 11.10 as guest. I'm using the latest version of VirtualBox.

The networking works fine, as installation completed correctly and I can browse web pages. I had issue of BADSIG 40976EAF437D05B5 when I used apt-get. I tried all the workarounds in the web (clearing cache, installing aptitude, removing files from /var/lib/apt/lists/partial, getting the key again, disabling IPv6, etc). I don't see the BADSIG error now. But I get the following error when trying to run apt-get update:

Unable to connect to[IP:]

I cannot ping to either. I can ping and it works.

Any pointers appreciated. thanks, bsr

cat /etc/resolv.conf  
 nameserver 10.240.0.x  

where, etc. are valid values.

I get two different IP addresses for that query:

Non-authoritative answer:

I am also able to ping both.

What settings are you using for your network on VirtualBox? Bridged or NAT?

What, if any, settings are on your Windows 7 firewall?

I would try using a bridged connection and for testing turn the Windows firewall off briefly. (Assuming you are behind a NAT firewall.)
