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
sudo apt-get update
on the terminal, the following kept occuring:

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.

And the following is for cat /etc/resolv.conf:
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.0.1
search nip.upd.edu.ph
It has been pointed out that the answer is here but unfortunately that didn't work either. 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
Server: 127.0.0.1
Address: 127.0.0.1#53
Output of ps aux | grep dns:
nobody 1761 0.0 0.0 33012 1284 ? S 17:04 0:00 /usr/sbin/dnsmasq
--no-resolv --keep-in-foreground --no-hosts --bind-interfaces --pid-file=/var

joa 2197 0.0 0.0 13576 928 pts/0 S+ 17:10 0:00 grep --color=auto dns
sudo apt-get update finally worked! I just realized that the problem was not on the system but instead how the system connects and retrieves data from the internet. I just configured my Network settings and changed the proxy detection to Manual and filled in the HTTP, HTTPS, FTP, and Socks Host blanks the proxy that I use. When I updated again, this error output happened at first:
E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/)
Well, not exactly like the same but similar to it (I copied above from here). But when I tried updating again, it finally worked(the reason I posted the error output above and not the exact output I saw) and I can now choose a different mirror server. If the Network proxy configuration was really the reason for my woes, well, I kinda felt stupid for such basic mistake.
Anyway, thanks everybody for your help! :)
