[ubuntu] Virtual Machine Unable to Update

view story

http://ubuntuforums.org – Hi, I am running 12.04 in virtualbox 4.1.8. When I try to download and install updates, I get the error that it "Failed to Download package files" and that I should check my internet connection. Internet is working (I am posting this from the virtual machine). The details output is as follows: Code: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/b/bind9/bind9-host_9.8.1.dfs... 404  Not Found [IP: 80] Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/b/bind9/dnsutils_9.8.1.dfsg.... 40 (Hardware)
