Which version are you running? Might as well make sure your system is fully updated.

yum update
yum groupinstall "GNOME Desktop"

To have Gnome start at boot run the command
systemctl set-default graphical.target

Well, obviously there is no group named X Window System.

It says that Server with GUI is already installed, so you should have X installed already. Try systemctl isolate graphical.

Hi,

Thanks for the reply. I have verified with my colleague machine and I could see "X Window System" in installed groups. But when I try to install I'm getting the error which I reported earlier and the group and the env also differs.

I have run the commands which you have mentioned below. I'm running CentOS Linux release 8.1.1911 (Core).

Could it be that your colleague is running a different Centos version? And/or using different repositories?

This is the start of your colleague's list:
And this is yours:
Do you see how different they are?

Your colleague probably has enabled additional repositories that supply some of the listed groups. The option -v / --verbose when used together with dnf group info will show what repositories the packages in a group are from.

Using the same option with dnf group list will show group IDs in the parentheses after group names. They are locale-agnostic and could be used in dnf group commands instead of group names.

Yes, he is using different version. Now I just want to install xming in my linux machine. When I install it gives me below error.

[root@twatsc-l130 database]# yum install xming
CentOS-8 - AppStream 9.5 kB/s | 4.3 kB 00:00
CentOS-8 - Base 17 kB/s | 3.8 kB 00:00
CentOS-8 - Extras 4.9 kB/s | 1.5 kB 00:00
No match for argument: xming
Error: Unable to find a match: xming

Any idea to get out of this error please?

Isn't Xming a Windows-only software? On Linux, you just use either X.org X11 or Wayland.

You can't expect yum to just install any name you give it. You have to give it the correct name. To find the correct name, try yum search WHATEVERSOFTWAREYOUWANTTOINSTALL. If that is not successful, use the internet.

I agree with shruggy that xming is for Windows. Why do you want to install it on the Linux server? Why not yum groupinstall "Server with GUI" or something similar?

yum groupinstall 'X Window System'
