I have successfully installed an OL 8.3 system, but I cannot find the usual Gnome RPM Manager. How do I installed it?
There is a software installation manager but it cannot manage individual RPM file.
Thanks for your attentions.
There isn't one in OL8 (or RHEL8 or CentOS8). The GNOME Software Manager is it. You will need to use dnf via the command-line instead.
