A «failed to fetch» error occurs when apt-get update is run. How do I fix this?
Contrary to the note above, I haven’t found the answer to my problem. I have read almost a dozen apt-get update questions, most from askubuntu.com, with «failed to fetch» errors and tried the solutions answered there. Unfortunately, none worked. I just recently installed Ubuntu 12.04 on my laptop, dual booting it alongside Windows 7. When i tried

They have been ignored, or old ones used instead. Note: This happened immediately after I installed Ubuntu 12.04. I am very new to the Linux/Ubuntu world and a noob when it comes to these kind of stuff. The Sources list in the Update Manager (and Software Center) settings was short. It only contained 2 lines with «Canonical» in it, 2 lines with «Independent» in it, and 2 other lines. I think the list was short because it was a freshly installed Ubuntu. Connection to the internet seems fine and my friend whose laptop had just been installed with Ubuntu 12.04 around the same time as mine, seems to have no problem with his update. We share the same connection so I think internet connection issues couldn’t have been the reason for the error. Attempted Solutions: From here, I explored around /etc/resolvconf/resolv.conf.d and added in the /etc/resolvconf/resolv.conf.d/head the following:
nameserver 8.8.8.8 nameserver 8.8.4.4 Error still occured. From here and here, I repeatedly changed which Mirror server to use in the Update manager and Software sources settings. Again, error still occured. I also tried editing my sources list, unchecking the lines with «independent» on it(as suggested). According to here, I tried removing the derb-src lines in the sources list. Still, to no avail. Lastly, this site suggests running the following:
echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null or, for a permanent solution, echo "nameserver 8.8.8.8" | sudo tee /etc/resolvconf/resolv.conf.d/base > /dev/null Sadly, nothing worked for me. In all forums that I have been to, the answer related to nameserver 8.8.8.8 seems to come up most often. Take note also that I really did not understand the solutions, what they meant or how are they done. I just simply followed them. This is the output for cat /etc/apt/sources.list :

I tried choosing different servers but the «choose server» was never available. Searching for the best server yielded a «No suitable server» result. I think the mirror servers are fine and again, there seems to be no issue with internet connection. Using ping -c3 archive.ubuntu.com and ping -c3 8.8.8.8 both yielded 0% packet loss . The ping for 8.8.8.8 sometimes yielded 33% packet loss but mostly 0%. Typing nslookup google.com yields
