when I tried to use imagefromjpeg() function in PHP,it throwed error.So, I tried to install GD library using the following command:
sudo apt-get install php5-gd
But I got the following error.
php5-gd : Depends: php5-common (= 5.5.9+dfsg-1ubuntu4) but 5.5.10+dfsg-1+deb.sury.org~saucy+1 is to be installed
E: Unable to correct problems, you have held broken packages.
I am using Ubuntu 14.04LTS. I recently upgraded my OS from ubuntu 13.10.
How to overcome this error?

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:
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-gdfrom 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-gdhas been installed from there and all your other php packages should have been upgraded to the Ubuntu 14.04 ("trusty") versions from the ppa.
