CentOS - Apr 2018 - Help with yum

I just did a fresh minimal install of centos 7 on new hardware. While 
playing around with window systems I removed X windows like so:

 >yum remove "X Window system"

and then tried to re install

 >yum group install "X Window system"

which gives this error:

Maybe run: yum groups mark install (see man yum)
No packages in any requested group available to install or upgrade

I tried running:

 >yum groups mark install "X Window system"

and get the same message. I tried different permutations removing the 
"s" on groups. Nothing seems to bring back the yum "X Window
system"
group. Can anyone help me resolve this issue and tell me what I did wrong?

Thanks for your help.

yum grouplist
does not show "X Window system" for me, on CentOS 7.

yum remove "non existent stuff"
gives me

Warning: group non existent stuff does not exist.
Maybe run: yum groups mark install (see man yum)
Error: No packages in any requested group available to install or update

That seems consistent with what you get.

HTH,

Kay

When you install a minimal system, you get no X.

As for pruning the system, I wrote a script to do that a while ago,
which works perfectly.

("elaguer" means "to prune")

Cheers,

Niki

Try

	yum group install "X Window System"

Note the capital 'S'.

First, thanks for everyone who tried to help me with this problem. At 
this point I will apologize to the list for what I think is just user 
error. Indeed I have convinced myself that there is no group package "X 
Window system" albeit one may have existed many years ago. For those who 
are interested in the full story continue reading other please accept my 
apology and many thanks for the list help.

Second, here is the full story. I wanted to install Mate after doing a 
minimal install. All the documentation I found on the web indicated that 
after enabling the epel repository I should do this sequence of yum 
commands(or something equivalent):

 > sudo yum groupinstall "X Window system" -y
 > sudo yum groups install "MATE Desktop" -y

Unfortunately I did things in opposite order and when I tried to do

 > startx

X windows would not startup. I swear that the after doing the "yum 
groupinstall "X Window system" that packages were downloaded and 
installed. So I chalked up the X start failure to doing things in the 
incorrect order. So this morning I thought I would start with a clean 
slate and did:

 > yum groupremove "X Window system" "MATE Desktop"
 > yum groupinstall "X Window system"

That is when I received the error message I did in my first post. So 
just now I went back to another CentoOS 7 system running Mate and 
re-produced the yum commands. It turns out the history contained 
everything I needed. In my case I just needed to install the elrepo to 
get the Nvidia drivers for my video card and first installed those:

 > yum install kmod-nvida nvidia-x11-drv

Then it was just a matter of:

 > yum groupinstall "MATE Desktop"
 > systemctl set-default graphical.target
 > reboot

Voila... I have a desktop running MATE!

I think the web instructions I found are outdated (although one web page 
was dated 2/18/2018. There doesn't exist a "X Window system" yum
group.
Generally I tell people when stuff like this happens that digital 
computers can't lie... next time I will take my own advice.

Again thanks to everyone who helped... Your time was appreciated.
