To install CUBRID Manager using apt-get on Ubuntu, we need to add CUBRID's repository so that Ubuntu knows where to download the packages from, and then tell the OS to update its indexes.
sudo add-apt-repository ppa:cubrid/cubrid sudo apt-get update
If you plan to use CUBRID Manager on your local computer, you only need the CUBRID Manager Server. For remote database administration, the CM Client is not required. CUBRID Manager Server is installed automatically when you install the CUBRID package.
Now install the latest version of CUBRID Manager (Client). This assumes that you are installing CM Client on Ubuntu Desktop version, since CM is a GUI application. CM Client will not run on Ubuntu Server so it is not required. Currently, this package exists only for CUBRID 8.4.0.
sudo apt-get install cubrid-manager-8.4.0
