RH9 is supported according to [Platform Notes 6.10 — OpenNebula 6.10.0 documentation](https://docs.opennebula.io/6.10/intro_release_notes/release_notes/platform_notes.html). I’m unable to install Opennebula 6.10. ruby-libs-3.0 is required, ruby-libs-3.3 is installed. Downgrading also removes rubygem-psych. rubygem-psych is also required by Opennebula. This would reinstall ruby-libs.3.3. How can I resolve the dependencies to successfully install Opennebula. The Rh8 repositories would also install ruby-libs-3.3. yum install opennebula … … package opennebula-6.10.0-1.el9.x86\_64 from opennebula requires opennebula-tools = 6.10.0, but none of the providers can be installed - package opennebula-tools-6.10.0-1.el9.noarch from opennebula requires opennebula- rubygems = 6.10.0, but none of the providers can be installed - conflicting requests - nothing provides libruby.so.3.0()(64bit) needed by opennebula-rubygems-6.10.0- 1.el9.x86\_64 from opennebula rpm -qa | grep ruby-libs ruby-libs-3.3.0-1.module+el9.4.0+21222+faeeed2f.x86\_64 cat /etc/os-release NAME=“Red Hat Enterprise Linux” VERSION=“9.4 (Plow)” … ---

You need to enable the repo which contains the missing dependencies ```bash repo=$(yum repolist --disabled | grep -i -e powertools -e crb | awk '{print $1}' | head -1) yum config-manager --set-enabled $repo && yum makecache ``` you should be able to install the `opennebula` package then ---

Hello dclavijo, “yum repolist” shows the repositories base, appstream, crb, epel, opennebula. The error messages are unchanged. The versions of the nodejs and libruby packages **are too new**!! Installing opennebula requires older packages, but downgrading is not possible. Then other necessary packages would be missing(for example rubygem-psych). _rpm -qa | grep -e nodejs -e ruby-lib_ _ruby-libs-3.3.0-1.module+el9.4.0+21222+faeeed2f.x86\_64_ _nodejs-docs-20.11.1-1.module+el9.3.0+21385+bac43d5a.noarch_ _nodejs-20.11.1-1.module+el9.3.0+21385+bac43d5a.x86\_64_ _nodejs-full-i18n-20.11.1-1.module+el9.3.0+21385+bac43d5a.x86\_64_ Best Regards.

Not sure how you ended up with those newer versions of dependencies. Perhaps this will help as a reference regarding what it is supposed to be installed and where does it come from ![image](https://canada1.discourse-cdn.com/flex031/uploads/opennebula/original/2X/a/aa00cc4e8e33e22b1d0991ba855d4c570482af48.jpeg) ![image](https://canada1.discourse-cdn.com/flex031/uploads/opennebula/original/2X/7/7e01d7db0a30ae126cbbc208b48db4eaf89d32b4.jpeg) ![image](https://canada1.discourse-cdn.com/flex031/uploads/opennebula/original/2X/1/19b7ea6acca3e9b4a87beeac8fca783f1f3d81a9.jpeg) ![image](https://canada1.discourse-cdn.com/flex031/uploads/opennebula/original/2X/7/770acf75738bd79a755583ca85e099fe4da159a5.jpeg) ![image](https://canada1.discourse-cdn.com/flex031/uploads/opennebula/original/2X/f/f4f6f6d8eca36a98caab34f221652be809fbb71a.png) ---

Hello, I found my mistake and was able to fix part of the problem. The software repos are provided by Suse Manager Repos. I had only assigned the patch repos, not the base repos. So I was able to downgrade corresponding packages and install opennebula, except package opennebula-fireedge. ```auto yum install opennebula-fireedge Updating Subscription Management repositories. Unable to read consumer identity This system is not registered with an entitlement server. You can use "rhc" or "subscription-manager" to register. Last metadata expiration check: 0:17:39 ago on Sun 22 Sep 2024 10:57:45 PM CEST. Error: Problem: conflicting requests - nothing provides nodejs(abi16) **>= 16.14** needed by opennebula-fireedge-6.10.0-1.el9.x86_64 from opennebula_6-10 - nothing provides nodejs(v8-abi9) >= 9.4 needed by opennebula-fireedge-6.10.0-1.el9.x86_64 from opennebula_6-10 (try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages) ``` After running “yum downgrade nodejs” several times, the lowest version of RH 9 nodejs-18.10 is reached. This is greater than the required version 16.14, but is not accepted by opennebula-fireedge. How can I solve? ```auto yum downgrade nodejs ... Downgraded: nodejs-1:18.10.0-3.module+el9.1.0+16866+0fab0697.x86_64 nodejs-docs-1:18.10.0-3.module+el9.1.0+16866+0fab0697.noarch nodejs-full-i18n-1:18.10.0-3.module+el9.1.0+16866+0fab0697.x86_64 npm-1:8.19.2-1.18.10.0.3.module+el9.1.0+16866+0fab0697.x86_64 Complete! yum downgrade nodejs Updating Subscription Management repositories.

Last metadata expiration check: 0:16:27 ago on Sun 22 Sep 2024 10:57:45 PM CEST. Package ***nodejs of lowest version already installed, cannot downgrade it***. Dependencies resolved. Nothing to do. ``` Best Regards Manuela
