GPaste is a clipboard management tool for GNOME 3. It is not available in the repos and must be downloaded via git and compiled. Here is how you can do it:
GPaste is now available in the repos, so you can install it by using Add/Remove Programs or by running the following commands in the terminal:
su yum install gpaste
That should install GPaste. The following post is for historical reasons only.
su -c 'yum install git'
Download GPaste sources
cd; git clone https://github.com/Keruspe/GPaste.git
su -c 'yum install gtk3-devel glib2-devel intltool automake autoconf vala'
Compile and Install
cd;cd GPaste ./autogen.bash ./configure --prefix=/usr make su -c 'make install'
Restart GNOME Shell
To restart, press Alt+F2, enter ‘r’ (without quotes) and press enter.
You should now see GPaste icon in the top panel.
