Oracle Linux 8: Minimal to Graphical installation procedure • • APPLIES TO: • Linux OS - Version #Oracle Linux 8.0 and later / #RHEL8 • • GOAL: • This note explains how to install GUI on Oracle Linux 8. Since during installation, this GUI package was not selected at the software selection phase. And so after installation, the screen boots into CLI prompt and not GUI. • When checked with the Available Environment Groups in grouplist it still shows Server with GUI as shown in an example below: • • #dnf grouplist • This system is receiving updates from Unbreakable Linux Network or Spacewalk. • Last metadata expiration check: x:yy:zz ago on Mon xx Oct yyyy • Available Environment Groups: • Server with GUI • SOLUTION: • 1. Ensure all the system packages are up to date. Execute the following command to update the system to the latest Oracle Linux 8 release from ULN • dnf update • 2. Execute the following to install the environments for GUI. • dnf groupinstall Server with GUI • The above will install the GUI with the OL8 which by default get installed to text mode. • 3. Enable GUI on system start up. In OL8, systemd uses ‘targets’ instead of runlevels. • Issue the following command to enable the GUI on system start. • ln -sf /lib/systemd/system/runlevel5.target /etc/systemd/system/default.target • 4. Reboot the machine and it will boot into GUI.
