Help With Yum

CentOS 8 Comments

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,

    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”)

  • 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.

    You have to write it “X Window System” with a capital S.

    Here’s my script that installs a bells-and-whistles Xfce desktop starting from a minimal CentOS 7 installation. Look at the X Window System section halfway through the script.

    Glad you got it working.

    I thought I’d mention that the reboot is not strictly necessary. The command

    yum isolate graphical.target

    will switch the system immediately to the named target.
