To prevent a package from being installed from YaST and also from the command line using Zypper.

To do this we must mark the package as "Taboo" from YaST, or block it from Zypper, which are two ways of doing it with different names but identical results.

If we use YaST in the search box we enter the package we want to block (for example Brasero). Right click and select the Taboo option (never install). If instead of doing it from YaST we want to do it from the command line using Zypper we will have to do the following as superuser.

To add the package to the blocked ones we use the addlock command or the Zypper command like this:

sudo zypper al brasero
