To update installed packages for security on a SUSE 15 system, you can use the zypper command. zypper is the default package manager for SUSE systems, and it can be used to manage packages and perform various package-related tasks.
To update installed packages for security on a SUSE 15 system, you can use the following zypper command:
sudo zypper update --type patch --security
This command will update all installed packages with security updates (i.e., patches). The --type patch option specifies that only patches should be installed, and the --security option specifies that only security-related patches should be installed.
It's worth noting that this command may take some time to run, depending on the number of packages that need to be updated and the speed of your system. You may also be prompted to confirm the installation of certain packages or to resolve any conflicts that may arise during the update process.
You can use the zypper command to perform other package-related tasks as well. For example, you can use the zypper search command to search for packages, the zypper install command to install new packages, and the zypper remove command to remove installed packages. You can use the zypper help command to see a complete list of available zypper options and learn more about how to use the command.
