Rocky 9.x Upgrade Rocky 8.x to Rocky 9.x

Home > Rocky Linux or CentOS > Rocky Linux 9.x > System Administration > Upgrade Rocky 8.x to Rocky 9.x

To upgrade from Rocky 8 to Rocky 9 use:

1. Ensure sufficient free space in / before proceeding
2. Full update current system

   dnf update -y --skip-broken --nobest --allowerasing

3. Consider doing below till it succeeds:

   sudo dnf upgrade --refresh

   If you neeed to remove some package for above to work then after every single removal try above command again till it completes successfully.

4. A few articles suggested doing:

   cd /etc/yum.repos.d
   rm -f CentOS* _copr* weewx.repo zmrepo*
   mv -f Rocky-PowerTools.repo.rpmnew Rocky-PowerTools.repo

5. Go to URL https://download.rockylinux.org/pub/rocky/9/BaseOS/x86_64/os/Packages/r/
6. Note package names for rocky-release, rocky-repos and rocky-gpg-keys. Eg at time of this writing values were:

   REPO_URL="https://download.rockylinux.org/pub/rocky/9/BaseOS/x86_64/os/Packages/r"
   RELEASE_PKG="rocky-release-9.2-1.5.el9.noarch.rpm"
   REPOS_PKG="rocky-repos-9.2-1.5.el9.noarch.rpm"
   GPG_KEYS_PKG="rocky-gpg-keys-9.2-1.5.el9.noarch.rpm"

7. Remove packages that may cause conflict:

   dnf -y remove rpmconf yum-utils epel-release

8. Install the rocky9 packages using:

   sudo dnf install $REPO_URL/$RELEASE_PKG $REPO_URL/$REPOS_PKG $REPO_URL/$GPG_KEYS_PKG

9. Move redhat-logos as it causes update to fail

   mv /usr/share/redhat-logos /usr/share/redhat-logos-old

10. Upgrade system from Rocky 8 to Rocky 9 via:

    sudo dnf --releasever=9 --allowerasing --setopt=deltarpm=false distro-sync -y

    If above throws errors then please try

    dnf remove openssl3-libs
    dnf remove python39-six
    dnf remove epel-release
    dnf remove libvpx6 iptables-ebtables

    • As a last resort you can consider running:

      sudo dnf --releasever=9 --allowerasing --setopt=deltarpm=false distro-sync -y --skip-broken --nobest

11. Rebuild the RPM DB using below after OS version is upgraded to 9 from 8:

    sudo rpm --rebuilddb

12. Optionally you can allow SHA1 based signatures via:

    update-crypto-policies --set DEFAULT:SHA1

    https://www.redhat.com/en/blog/rhel-security-sha-1-package-signatures-distrusted-rhel-9

13. Optionally If using dnf generates warnings such as:

    Problem 1: conflicting requests
    - nothing provides module(platform:el8) needed by module container-tools:rhel8:8080020230516204140:8108cfbc.x86_64
    ...

    for many modules then list and remove modules which depend on platform:el8. For example

    dnf module list
    dnf module disable container-tools gimp httpd llvm-toolset mariadb nginx nodejs perl perl-DBD-MySQL perl-DBI perl-libwww-perl php postgresql python27 python36 python38 python39 satellite-5-client virt perl-DBD-SQLite perl-IO-Socket-SSL

14. Verify latest 5.14 kernel got installed properly using:

    dnf -y install kernel kernel-core shim epel-release

15. Full update system once again using:

    dnf update -y --nobest --allowerasing --skip-broken
    dnf install neofetch -y

16. Reboot system and validate Rocky 9 with 5.14 kernel
17. Only if boot via 5.14 kernel is successful check and remove older kernel using:

    dnf remove $(rpm -qa|grep -i kernel|grep 4.18)

18. Also install any critical packages removed earlier via dnf
