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
