For a 32 bit system:
Press Ctrl+Alt+T on the keyboard to open the terminal. When it opens, run the command below to update your package lists:
sudo apt-get update
Then open the Ubuntu Software Center, search for and install the package flashplugin-installer.
It extracts the 32-bit Flash player library from the adobe-flashplugin package (which is retrieved from http://archive.canonical.com/) and configures itself as default for Internet browsers.
For a 64 bit system:
Because flashplugin-installer installs the 32-bit version of Flash and a related compatibility library which may be slower and less stable, it’s recommended to install the adobe-flashplugin package from the Canonial partners repository.
First open Software & Updates from the Unity dash, then enable the partners repository under the Other Software tab.

After that, press Ctrl+Alt+T on the keyboard to open the terminal. When it opens, run the commands below to install flash:
sudo apt-get update
sudo apt-get install adobe-flashplugin
If it still fails(installation candidate not found), its possible that canonical sources were not added. You can try change it manually by un-commenting the lines containing canonical source links in the file /etc/apt/sources.list
