Failed to fetch APT update (Not a duplicate)

Question

I've already checked this, this and this answers, none of them works in my case. Here is what I'm getting when I run sudo apt-get update on my 14.04 LTS laptop:

W: Failed to fetch http://us.archive.ubuntu.com/ubuntu/dists/trusty/main/binary-i386/Packages  Hash Sum mismatch

E: Some index files failed to download. They have been ignored, or old ones used instead.

I've already tried sudo apt-get clean followed by rm -rf /var/lib/apt/lists before doing an update again, but it didn't work. Here are the repos which are enabled in sources.list:

deb http://us.archive.ubuntu.com/ubuntu/ trusty main
deb http://us.archive.ubuntu.com/ubuntu/ trusty universe
deb http://security.ubuntu.com/ubuntu trusty-security main
deb http://security.ubuntu.com/ubuntu trusty-security universe
deb http://security.ubuntu.com/ubuntu trusty-security multiverse
deb http://us.archive.ubuntu.com/ubuntu/ trusty-updates main universe multiverse

EDIT

As I explained in the comments, the answer to the linked question didn't work out for me. I've already tried removing the lists folder and running apt-get clean

Answer 1

Firstly, I generated a clean and minimal sources.list from repogen having only main and universe sections. Then, I made a thorough reset of my apt system by following:

sudo apt-get clean
sudo rm -rf /var/lib/apt/lists/
sudo apt-get update --fix-missing

But even that didn't solve the problem. Then I located the problem source to the universe section of the repo line in sources.list:

deb http://in.archive.ubuntu.com/ubuntu trusty main
#deb http://in.archive.ubuntu.com/ubuntu trusty universe

I found that after commenting the universe section, apt-get update worked without any problems, but with universe added, I was getting this error:

W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/Release  Unable to find expected entry 'universe/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file)

Then as per the suggestion of @FlorianDiesch, I tried switching the servers: I tried the main, Indian and American ones, but with no luck:

deb http://archive.ubuntu.com/ubuntu trusty universe
deb http://in.archive.ubuntu.com/ubuntu trusty universe
deb http://us.archive.ubuntu.com/ubuntu trusty universe

Finally, the I tried the German server and it paid off!

deb http://de.archive.ubuntu.com/ubuntu trusty universe

Now, apt-get update did a proper update without any issues. This seems to suggest that either the Release files of the other servers have some issues in them or they just don't like my machine setup for some reason.
