I am using Ubuntu 14.04LTS. I recently upgraded my OS from ubuntu 13.10. How to overcome this error?

Solution

It seems you have installed PHP via launchpad PPA:

https://launchpad.net/~ondrej/+archive/php5

Check your apt sources.list if the ppa is still active. On 14.04, you should have these repos active:

deb http://ppa.launchpad.net/ondrej/php5/ubuntu trusty main 
deb-src http://ppa.launchpad.net/ondrej/php5/ubuntu trusty main 

Explanation:

It seems you had the additional PHP-launchpad repository added before, but it was deactivated during dist-upgrade. Because of that, apt tried to install php5-gd from the standard debian repo, but this version also needs a standard php-common as dependency (which you don't have). By activating the launchpad repo again, php5-gd has been installed from there and all your other php packages should have been upgraded to the Ubuntu 14.04 ("trusty") versions from the ppa.

@etagenklo I have updated your output in the question

[etagenklo]

You should not enter this in the shell, you should check the files in /etc/apt/sources.list and /etc/apt/sources.list.d/ for these entries and add them if neccessary.

[Ganesh Babu]

I've added those lines in the file you've specified. But still I didn't find it working

[etagenklo]

Did you issue sudo apt-get update before trying it again?

[Ganesh Babu]

Thank you very much. Your solution clearly worked out for me. But still I can't understand what has happened. Have I upgraded my PHP or Have I reinstalled my PHP?

[etagenklo]

I've updated my answer with an explanation.

Response from Etagenklo should be valid, though in my case after adding the PPA's it not only installed php5-gd and php5 common, but it also installed a lot more of extensions. Though it was expected it also try to install new available php.ini's. Take this into serious consideration: If you run this into production server and you have your own edits on ini files you should always want to preserve the installed ones. Overwrite the original may lead your website goes down.
