Remove The GNOME GUI on RHEL 7 Centos 7 Fedora and Oracle Linux Server

[root@RHEL7HARDEN ~]# rpm -qa yum
yum-3.4.3-132.el7.centos.0.1.noarch
[root@RHEL7HARDEN ~]#

 

I captured the list of ‘Warning: group <groupname> does not exitst.’ (see previous post) from a ‘yum update’ run which I CTRL+c out of once the warnings ended.
I removed the ‘Warning: group ‘ from the front and the ‘ does not exitst.’ from the back and then put the result into a variable.

[root@RHEL7HARDEN ~]#  yum groupremove ‘X Window System’ ‘GNOME’
Loaded plugins: fastestmirror, langpacks
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)

I had gone for the ‘yum groups mark remove’ way some days ago when I was hit by that issue…

It looks like setting upgrade_group_objects_upgrade=0 or group_command=simple in /etc/yum.conf resolves this issue.

#  This is the default, if you make this bigger yum won’t see if the metadata
# is newer on the remote and so you’ll “gain” the bandwidth of not having to
# download the new metadata and “pay” for it by yum not having correct
# information.
#  It is esp. important, to have correct metadata, for distributions like
# Fedora which don’t keep old packages around. If you don’t like this checking
# interupting your command line usage, it’s much better to have something
# manually check the metadata once an hour (yum-updatesd will do this).
# metadata_expire=90m

# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d
