I'm running Ubuntu 10.04 on a desktop with an Edimax EW-7811UN wireless USB adapter. I just got the computer online earlier today. My internet source is tethered from my Android smartphone, so it can be a bit slow at times, but it works. Except when I try to get new software from the Ubuntu Software Center. Downloads reach 50%, then suddenly stop with a message telling me to check my internet connection, and this: "Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/s/samba/winbind_3.4.7~dfsg-1ubuntu3.8_i386.deb 404 Not Found [IP: 91.189.92.200 80]"
iwconfig gives this reading:
Code:
jacob@jacob-desktop:~$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.

And ifconfig gives this reading:

I'm still new to Ubuntu, and so I have no idea why this dialog appears or what to do about it. Any help would be highly appreciated!
