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 security.ubuntu.com[IP:91.189.92.166]

I cannot ping to 91.189.92.166 either. I can ping www.google.com and it works.

Any pointers appreciated. thanks, bsr 

cat /etc/resolv.conf  
 domain abc.be  
 search abc.be  
 nameserver 10.240.0.x  
 nameserver 193.xx.xxx.55

where abc.be, etc. are valid values.

I get two different IP addresses for that query:

Non-authoritative answer:
 Name:     security.ubuntu.com
 Address:  91.189.92.167
 Name:     security.ubuntu.com
 Address:  91.189.92.166

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.)
