1. you can downgrade your installed packages with this code :
   
   dpkg -i --force-downgrade /var/cache/apt/archives/APPLICATION-NAME-#
   
   # : means the version number currently installed.
   


2. you can remove your package with :
   
   dpkg -r APPLICATION-NAME-#
   
   and then download desired version in .deb format, and install it.
   



3. Your system generally has multiple versions of a package available in its repositories ,It means when Ubuntu updates a package, it places the new, updated package in a special updates repository. The old package is still located an Ubuntu’s main repository and can be installed with a few tricks. If you’ve installed a newer version of a package from a personal package archive (PPA), the older packages included with Ubuntu are still located in Ubuntu’s repositories.
   
   if you use Synaptic for managing your Packages, you can do this :
   

   
   
   
   
   

   • search for application you want and select it :
     
     

   
   

   • from menu select Package and select Force Version :
     
     

   
   

   • new window opened and you can select which version you want, and click on Force Version button :
     
     

   
   
   • now this window closed and you return to Synaptic window, and you see the red icon inside the application checkbox, and Apply button now enabled, click on Apply to apply your changes :
     
     
   
   

NOTE : After downgrade this package, select it and go to Package menu and select Lock Version option. If you don’t do this, Ubuntu will try to upgrade the installed package the next time you update your installed packages.
