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. Go to URL https://download.rockylinux.org/pub/rocky/9/BaseOS/x86_64/os/Packages/r/
4. 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"

5. Remove packages that may cause conflict:

   dnf -y remove rpmconf yum-utils epel-release

6. Install the rocky9 packages using:

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

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

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

8. 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:

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

9. If there are still errors we may have to remove those packages. For example

   dnf remove openssl3-libs
   dnf remove python39-six
   dnf remove epel-release

   and then try distro-sync again. Note the names of packages being removed including the ones getting removed due to dependency. We may have to install them again later.

10. Rebuild the RPM DB using:

    sudo rpm --rebuilddb

11. Check if there is older kernel using:

    rpm -qa | grep -i kernel

    If the above list contains older 4.18 kernel instead of new 5.14 kernel then old can be removed via:

    rpm -e --nodeps  `rpm -qa|grep -i kernel|grep 4.18`

12. Optionally install latest 5.14 kernel using:

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

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. Full update system once again using:

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

15. Reboot system and validate Rocky 9
16. Optionally you can allow SHA1 based signatures via:

    update-crypto-policies --set DEFAULT:SHA1

17. Also install any critical packages removed earlier via dnf
