When I try to install openjdk-7-jdk, I get the following message:

Failed to fetch http://in.archive.ubuntu.com/ubuntu/pool/main/o/orbit2/liborbit2_2.14.19-0.2_amd64.deb  
Size mismatch
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

How to fix it?

Try executing the following commands:

sudo apt-get clean
sudo apt-get update
sudo apt-get install openjdk-7-jdk

From man apt-get:

clean

Clears out the local repository of retrieved package files. It removes everything but the lock file from /var/cache/apt/archives/ and /var/cache/apt/archives/partial/.

So this will delete all local repository and retrieved packaging files using apt-get clean (forcing apt-get update to re-download everything), then re-downloading them using apt-get update (this will hopefully fix the size mismatch) and then installing openjdk-7-jdk using apt-get install openjdk-7-jdk.
