Yum update error

Latest response


I'm not able to update with YUM. What should i do?

yum update

Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
file:///cdrom/Server/repodata/repomd.xml: [Errno 14] curl#37 - "Couldn't open file /cdrom/Server/repodata/repomd.xml"
Trying other mirror.
No packages marked for update


It appears you have a repo in /etc/yum.repos.d which is looking for software on a mounted DVD. Remove the repo from /etc/yum.repos.d then try again.

I removed dvd.repo. But then it gave me this message.

Loaded plugins: langpacks, product-id, search-disabled-repos, subscription- : manager certificate verify failed

I solved the problem with in /etc/rhsm/rhsm.conf But now when i try to run "yum update" command, it just says "No packages marked for update" .

Is this normal? I'm sorry, i am quite new in this operating system.

I would re-enable certificate validation in /etc/rhsm/rhsm.conf. Which RHEL release are you using? Is your RHEL instance registered with RHSM or Satellite?

I'm using rhel 7 and yes i have already registered to the system. in /etc/rhsm/rhsm.conf, i changed "insecure=0 " to "insecure=1" . Do i have to set to 0 again?

Set to insecure=0. What are your settings for the fields below in /etc/rhsm/rhsm.conf?

repo_ca_cert = 
hostname = subscription.rhsm.redhat.com$
prefix = /subscription$
baseurl= https://cdn.redhat.com$
ca_cert_dir = /etc/rhsm/ca/$
repo_ca_cert = %(ca_cert_dir)sredhat-uep.pem$

Looks ok, except those $ characters at the end of each line.

Are there other repos defined in /etc/yum.repos.d? Have a look at Example 8.25. A sample /etc/yum.repos.d/redhat.repo file

I'm so sorry for the late reply. I looked there but i didn't see anything to solve the problem.

There are nly these repos defines in /etc/yum.repos.d : epel.repo epel-testing.repo google-chrome.repo redhat.repo

Check contents of redhat.repo cat /etc/yum.repos.d/redhat.repo. Are they enabled? should read enabled = 1

No, they are not. They all equal to 0. Do i need to change it all of them to 1 ?

Try changing them to 1.

I did and run the yum update command.

Another app is currently holding the yum lock; waiting for it to exit...
  The other application is: PackageKit

After that with "ps aux | grep yum" , i found the id and kill the process. And then i run the yum update again. Actually it works! But at the end it gave me the following error :

** Found 6 pre-existing rpmdb problem(s), 'yum check' output follows:

What is this and is this really important? I'm so sorry for the lots of questions and problems.

No action required for now. Red Hat are pursuing a fix for this.

See this KB - Package conflicts with ipa and freeipa

That's a relief! Thank you so much for your effort.

Have a great day !

Hi Comugeomatik, her the answer:



Hello Comugeomatik,

Did you run below command, before yum update? It might be that you hit cached repo info from the installer. yum clean all

Kind regards,

Jan Gerrit

Hi Jan,

Yes i did and nothing happen. But thank you for your attention.

Have a good day!
