Error: No matching repo to modify: crb {Oracle Linux 9 / Rocky Linux 9}

Rocky Linux General
1

Hello Team,

I have this challenge whenever I try to install the CRB repo on Oracle Linux 9 / Rocky Linux 9

My repolist looks like this:-

# dnf repolist
repo id repo name
ol9_UEKR7 Oracle Linux 9 UEK Release 7 (x86_64)
ol9_appstream Oracle Linux 9 Application Stream Packages (x86_64)
ol9_baseos_latest Oracle Linux 9 BaseOS Latest (x86_64)
ol9_developer_EPEL Oracle Linux 9 EPEL Packages for Development (x86_64)

I have installed the latest EPEL.
# dnf list installed | grep epel
oracle-epel-release-el9.x86_64 1.0-1.el9 @ol9_baseos_latest

Still, I have set my crypto-policies to DEFAULT

But every time I run the CRB command:
# dnf config-manager --enable crb
Error: No matching repo to modify: crb.

I get this error. This is the same case with my Rocky Linux 9 lab-machine.

Am trying to install KDE Desktop Environment on Oracle Linux 9, but this issue cant allow me to continue.

Please help.

Oracle Linux most likely has a different name for crb. You can check that by doing:

dnf repolist --all

and then see what is shown. For example on Oracle 8 it was called ol8_codeready_builder.

The command will work for Rocky 9 though, as I have used it:

[root@rocky9 ~]# dnf config-manager --enable crb
[root@rocky9 ~]# dnf repolist
repo id           repo name
appstream         Rocky Linux 9 - AppStream
baseos            Rocky Linux 9 - BaseOS
crb               Rocky Linux 9 - CRB
elrepo            ELRepo.org Community Enterprise Linux Repository - el9
epel              Extra Packages for Enterprise Linux 9 - x86_64
extras            Rocky Linux 9 - Extras

as you can see it’s clearly there. On Rocky 9 you can also do:

crb enable

or check it with:

crb status

that package comes from EPEL so make sure to do:

dnf install epel-release

And just in case you have some repo file corruption, the crb entries should be in /etc/yum.repos.d/rocky.repo and you should be able to see crb entries like below:

[crb]
name=Rocky Linux $releasever - CRB
mirrorlist=https://mirrors.rockylinux.org/mirrorlist?arch=$basearch&repo=CRB-$releasever$rltype
#baseurl=http://dl.rockylinux.org/$contentdir/$releasever/CRB/$basearch/os/
gpgcheck=1
enabled=1
countme=1
metadata_expire=6h
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-Rocky-9

[crb-debug]
name=Rocky Linux $releasever - CRB - Debug
mirrorlist=https://mirrors.rockylinux.org/mirrorlist?arch=$basearch&repo=CRB-$releasever-debug$rltype
#baseurl=http://dl.rockylinux.org/$contentdir/$releasever/CRB/$basearch/debug/tree/
gpgcheck=1
enabled=0
metadata_expire=6h
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-Rocky-9

[crb-source]
name=Rocky Linux $releasever - CRB - Source
mirrorlist=https://mirrors.rockylinux.org/mirrorlist?arch=source&repo=CRB-$releasever-source$rltype
#baseurl=http://dl.rockylinux.org/$contentdir/$releasever/CRB/source/tree/
gpgcheck=1
enabled=0
metadata_expire=6h
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-Rocky-9

if you are missing these in that rocky.repo file, then that would explain why, so you can copy and paste the above into your /etc/yum.repos.d/rocky.repo file to ensure that they exist and can be enabled/disabled. If they are missing, that would suggest your install method or ISO is corrupted as they are there by default normally.

You should verify that though using the dnf repolist --all command to see what repositories the system sees, enabled or disabled. But for Oracle, it will most likely have a different name, and not crb.

Running the “KDE Plasma Workspaces” command gives this output.

**# dnf groupinstall -y "KDE Plasma Workspaces"**
Last metadata expiration check: 0:01:25 ago on Fri 30 Dec 2022 03:55:25 PM EAT.
Module or Group 'KDE Plasma Workspaces' is not available.

Does this mean that its impossible to install KDE Plasma Desktop Environment on Oracle Linux 9?

Oracle? Does OL have its own community / documentation?

@Jil I’ve formatted your posts to make them more readable, please use the tools to format correctly, so it saves me having to do it :slight_smile:

But yeah, if you don’t have EPEL or whatever repo that provides “KDE Plasma Workspaces”, then no you cannot install it. I don’t know what provides that group but I assume EPEL. So maybe you didn’t install epel-release. I have crb and epel installed and I see it. Since EPEL relies on packages from CRB, then you should have both enabled. One, or the other, is not enough.

Most commands that work on Rocky will translate to Oracle Linux, maybe with different repo names at least as you found with CRB vs codereadybuilder (which crb is short for). Anything deeper with Oracle Linux, we cannot really help with since this is a Rocky forum, so the Oracle stuff should be asked in the Oracle community. Otherwise, pretty much everything should work between the two without problems other than name changes for certain things.

The “yum groups” are defined within repository metadata. All about KDE is in EPEL, so one does need to define&enable EPEL repository before its metadata is usable.

Rocky “extras” and Alma “extras” repos do provide epel-release for convenience.
I bet that RHEL does not and I have no idea what Oracle does.

The repoid that contains “EPEL” is probably not “the EPEL”:

ol9_developer_EPEL        Oracle Linux 9 EPEL Packages for Development (x86_64)

(It isn’t defined in /etc/yum.repos.d/oracle-linux-ol9.repo as far as I can see.)

Oracle provides their own “epel” where they likely pick and choose what they want from actual epel.

Thank you alot guys.

Yep, for RHEL, Oracle and others that don’t have it, easy just to follow instructions from the EPEL webpage on how to get it installed and running. TBH I think if I was using Oracle, I’d prefer the main EPEL one, than the one Oracle provides, especially if it’s a pick and choose of what they feel should be accessible.

I think it does provide the ability to enable it out-of-the-box, but it then says everything within it is not supported.

No, RHEL doesn’t provide EPEL to enable out of the box.

No matches found.

you have to add it using the instructions from EPEL’s page.

See: https://access.redhat.com/solutions/3358 where they explain exactly that in their own docs.

Many EPEL packages require the CodeReady Builder (CRB) repository.
It is recommended that you run /usr/bin/crb enable to enable the CRB repository.


sudo dnf upgrade

Enabling CRB.

sudo crb enable /usr/bin/crb

Then.

OK, I’ll need to check in more detail.
If you’ve still got access to the RH box, can you try

dnf repoquery --repoid "extras"

Can you explain your reasoning behind this command and why you are asking for it to be ran, and what you expect it to show? Extras has nothing to do with EPEL. Also:

[root@rhel9 ~]# dnf repoquery --repoid "extras"
Updating Subscription Management repositories.
Error: Unknown repo: 'extras'

Extras was something from RHEL7, but even then, it still had nothing to do with EPEL repository. It also mentions that in the Red Hat link I posted:

Sorry for confusion.

After checking in more detail, I can see that RH do NOT supply the epel repo out-of-the-box, so @jlehtone was right in the first place.
