I am a programmer and I can’t do without a clipboard manager. If you have never used a clipboard manager before, you don’t know what a great tool you are missing. GPaste is an excellent clipboard tool for Gnome-Shell, however it is neither available in Ubuntu repository, nor in any PPA (as of now). Here is how you can compile it. Open up the terminal and get going.
Install Dependencies
sudo apt-get install libgtk-3-dev libglib2.0-dev intltool automake autoconf valac git libdee-dev gnome-tweak-tool
Download Source
cd; git clone https://github.com/Keruspe/GPaste.git
Compile and Install
cd;cd GPaste ./autogen.sh ./configure --prefix=/usr make sudo make install
Restart Gnome-Shell
To restart, press Alt+F2, enter ‘r’ (without quotes) and press enter.
Enable GPaste Extension
To enable extension, open up Alt+F2>gnome-tweak-tool (or Activities>Applications>Other>Advanced Settings) and enable GPaste under Shell Extensions.

You should now see GPaste icon in the top panel. However, it may give the following error message:
(Couldn’t connect to GPaste daemon)
For this, add the GPaste daemon in startup as “gpaste –daemon” in StartUP applications and reboot.
