we are using rhel 7.6 version

we are very surprised that yum-config-manager isnt installed on rhel 7.6 by default

so we download the ISO file of rhel 7.6 , and mount all pkgs from rhel 7.6 to /mnt

and create the repo for rhel 7.6

so now we try to install the yum-config-manager

but:

yum install yum-config-manager
Loaded plugins: langpacks
configuration
No package yum-config-manager available.
Error: Nothing to do

so I not understand why this pkg/rpm isn't part of the ISO?

update , we did also

yum provides */yum-config-manager
Loaded plugins: langpacks
configuration
InstallMedia/filelists_db                                                                                                                                             | 3.4 MB  00:00:00

The yum-config-manager program is not a standalone package. It is part of yum-utils package, thus:

yum install yum-utils

  • its strange because I have - yum-utils-1.1.31-50.el7.noarch , but not yum-config-manager – yael May 9 at 18:48
  • Try reinstalling it, e.g. yum reinstall yum-utils. To make sure whether a given installed package provides the file you ned you can run: rpm -ql yum-utils | grep config-manager. To see which packages from the repos, provide the files you need you can also try yum provides */yum-config-manager – Danila Vershinin May 9 at 18:52
  • I did it but still not have yum-config-manager – yael May 9 at 18:54

    @yael your questions claims you seek yum-config-manager which has little relation to subscription manager. If you want subscription manager, you need subscription-manager as mentioned by @jsbillings – Danila Vershinin May 9 at 19:05

As the other answer says, it’s part of the yum-utils package. Any other missing package would most likely be on the supplementary binary DVD ISO. They can’t fit everything on an ISO that can be burned to a DVD.

If you are installing off a mounted ISO image and aren’t registering the system with redhat, why not just use the Everything ISO from CentOS? It’d be easier to use.

  • since you link that you gave is centos , then I guess yum-config-manager , it not part of any of the ISO files there , as you know yum-config-manager can activated only form tedhat OS – yael May 9 at 18:51
  • @yael no. It’s part of CentOS too. In fact, it’s easier to prove because I can link to the package itself: vault.centos.org/7.6.1810/os/x86_64/Packages/… – jsbillings May 9 at 18:59
  • I want to clear something , dose subscription-manager is part of yum-config-manager – yael May 9 at 19:01
  • It isn’t part of yum-utils but in the aptly named package subscription-manager. – jsbillings May 9 at 19:03
