Fedora 25: Workaround to install system-config-kickstart 1

Recently, we tried to install system-config-kickstart on a Fedora 25 x86_64 Workstation but it failed because dnf could not find an installation candidate for system-config-date.

The hack-ish solution

After reviewing the packages that were available at the time in https://kojipkgs.fedoraproject.org/packages/system-config-date/ we found the latest rpm version and we had dnf install that manually.
sudo dnf install https://kojipkgs.fedoraproject.org/packages/system-config-date/1.10.9/3.fc25/noarch/system-config-date-1.10.9-3.fc25.noarch.rpm python-kickstart system-config-kickstart;
The installation went smoothly and we were able to use system-config-kickstart.

Output of successful installation

sudo dnf install https://kojipkgs.fedoraproject.org/packages/system-config-date/1.10.9/3.fc25/noarch/system-config-date-1.10.9-3.fc25.noarch.rpm python-kickstart system-config-kickstart

How to Start/Stop or Enable/Disable firewalld on Fedora 25

firewalld (Dynamic Firewall Manager) tool provides a dynamically managed firewall. The tool enables network/firewall zones to define the trust level of network connections and/or interfaces. It has support both for IPv4 and IPv6 firewall settings. Also, it supports Ethernet bridges and allow you to separate between runtime and permanent configuration options. Finally, it supports an interface for services or applications to add firewall rules directly.

Disable firewalld

To disable firewalld, execute the following command as root or using sudo:

systemctl disable firewalld;

Enable firewalld

To enable firewalld, execute the following command as root or using sudo:

systemctl enable firewalld;

Stop firewalld

To stop (or deactivate) firewalld,execute the following command as root or using sudo:

systemctl stop firewalld;

Start firewalld

To start (or activate) firewalld, execute the following command as root or using sudo:

systemctl start firewalld;

Status of firewalld

To check the status of firewalld, execute the following command as root or using sudo:

systemctl status firewalld;


systemd provides a dependency system between various entities called “units” of 12 different types. Units encapsulate various objects that are relevant for system boot-up and maintenance. The majority of units are configured in unit configuration files, whose syntax and basic set of options is described in systemd.unit(5), however some are created automatically from other configuration, dynamically from system state or programmatically at runtime. Units may be “active” (meaning started, bound, plugged in, …, depending on the unit type, see below), or “inactive” (meaning stopped, unbound, unplugged, …), as well as in the process of being activated or deactivated, i.e. between the two states (these states are called “activating”, “deactivating”). A special “failed” state is available as well, which is very similar to “inactive” and is entered when the service failed in some way (process returned error code on exit, or crashed, or an operation timed out). If this state is entered, the cause will be logged, for later reference. Note that the various unit types may have a number of additional substates, which are mapped to the five generalized unit states described here.
— From man systemd

The above, in a nutshell:

  • enabled is a service that is configured to start when the system boots
  • disabled is a service that is configured to not start when the system boots
  • active is a service that is currently running
  • inactive is a service that is currently stopped and may be disabled, but it can be started and become active
