Dear Rocky Experts, I am trying to install a previous version of the “qemu-kvm” package on a Rocky 8.6 system. However, the version I want is no longer listed on the appstream repo, even with the “–showduplicates” option. Here’s what I see on my host after updating all packages from Rocky 8.5 to 8.6: ```auto # dnf --showduplicates list qemu-kvm Installed Packages qemu-kvm.x86_64 15:6.2.0-11.module+el8.6.0+1000+18e3b59f.5 @appstream Available Packages qemu-kvm.x86_64 15:6.2.0-11.module+el8.6.0+847+b490afdd appstream qemu-kvm.x86_64 15:6.2.0-11.module+el8.6.0+998+252a5635.2 appstream qemu-kvm.x86_64 15:6.2.0-11.module+el8.6.0+1000+18e3b59f.5 appstream ``` Looking on another 8.5 system (not yet updated) here’s what shows: ```auto #dnf list qemu-kvm Installed Packages qemu-kvm.x86_64 15:4.2.0-59.module+el8.5.0+670+c4aa478c @appstream Available Packages qemu-kvm.x86_64 15:6.2.0-11.module+el8.6.0+1000+18e3b59f.5 appstream ``` I need to get back to version 15:4.2.0 of qemu-kvm, due to an unresolved bug. How do I make this version available on my Rocky 8.6 system? Note: I tried modifying the Appstream repo.conf file with “baseurl=[http://download.rockylinux.org/vault/rocky/8.5/AppStream/$basearch/os/](http://download.rockylinux.org/vault/rocky/8.5/AppStream/%24basearch/os/)” but no dice. Any assistance would be greatly appreciated. -jm ---

Did you hash out the mirrorlist line? This must not be enabled - just making sure in case. Also, you might want to do: ```auto dnf clean all ``` and then see if it will pick up the vault url. Not sure if you tried that? ---

Aha! That did the trick! The mirrorlist _was_ still enabled. After fixing that, and a quick “dnf clean all”, I can now see the v4.2.0 package that I need. I installed v4.2.0-60 and now I see this: ```auto # /usr/libexec/qemu-kvm -version QEMU emulator version 4.2.0 (qemu-kvm-4.2.0-60.module+el8.5.0+772+743bb337.2) Copyright (c) 2003-2019 Fabrice Bellard and the QEMU Project developers ``` NOTE: I _did_ have to reboot before removing the v6.2 package. Even though ps showed no “qemu-kvm” processes running, “dnf remove qemu-kvm” completed without error, but the files were stil there. Only after rebooting and re-running “remove” were the files actually gone. Maybe some file locks… Weird, huh? Anyway, thanks for your help. -jm ---

For what it’s worth, the mirrorlist does also support older versions to be served. In the mirrorlist line, change the repo name (e.g. AppStream-8) to something like “vault-AppStream-8.5” See below: [https://mirrors.rockylinux.org/mirrorlist?repo=vault-AppStream-8.5&arch=x86\_64](https://mirrors.rockylinux.org/mirrorlist?repo=vault-AppStream-8.5&arch=x86_64) ---

If you edit the \*.repo files, they might not get dnf updated, only because the package will see them as dirty, and create something like \*.rpmnew. ---

gerry, Agreed. I don’t plan on leaving the “hacked” appstream repo def in place for long – just until I have the old packages I need. Then I will restore the default Rocky-AppStream.repo. However, I am adding this line, to prevent qemu-kvm (and its dependencies) from updating, until I resolve the issue I am having with v6.2.0: ```auto exclude=*qemu* edk2-ovmf seabios-bin seavgabios-bin sgabios-bin usbredir ``` ---
