How to upgrade

Follow these steps to upgrade CloudLinux 8.4 to 8.5 manually:

  1. Install updated cloudlinux-release package.
# dnf install -y https://repo.cloudlinux.com/cloudlinux/8.5/cloudlinux-release-latest-8.rpm
  1. Make sure that the /etc/yum.repos.d/cloudlinux.repo file is successfully updated. Now it should contain only the mentioned repos:
      • cloudlinux-updates-testing
      • cloudlinux-updates-testing-source
      • cloudlinux-updates-testing-debuginfo
      • cloudlinux-x86_64-server-8-source
      • cloudlinux-x86_64-server-8-debuginfo

If there are more repositories found, then you might have edited this file before. That means it wasn’t updated. Check if the /etc/yum.repos.d/cloudlinux.repo.rpmnew file is present and then rename it to /etc/yum.repos.d/cloudlinux.repo:

# mv /etc/yum.repos.d/cloudlinux.repo.rpmnew /etc/yum.repos.d/cloudlinux.repo
  1. Import AlmaLinux GPG key (or accept it later during the dnf update step)
# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-AlmaLinux
  1. Clean dnf cache
# dnf clean all
  1. Make sure your system has a subscription to CLN and the cloudlinux-x86_64-server-8 channel is available and contains many packages.
# dnf repoquery --repo cloudlinux-x86_64-server-8
  1. Now, your system is ready for the update.
# dnf update

Review dnf output and accept the update.

CloudLinux 8.5 repos have fewer packages than previous CloudLinux 8.x releases because the 8.5 version is rebased to AlmaLinux, which is 1:1 RHEL or CentOS and doesn’t provide several devel and static packages. These packages are in devel repo now that is disabled by default. If needed, you can enable devel repo while installing packages, though it is not recommended to update from it or enable it permanently. Here is an example:

# dnf --enablerepo=devel install bash-devel

Converting AlmaLinux/CentOS 8.5 to CloudLinux 8.5

You are able to convert AlmaLinux/CentOS 8.5 to CloudLinux 8.5 using our cldeploy script.

Known Issues

OVH uses a specific environment to boot kernels. In some cases, the default EFI partition needs to be reconfigured to boot the right default kernel. You can use the following article to reconfigure it: CloudLinux 7/8 kernel unable to boot on UEFI enabled soft raid 1 server.

There is a present grub2 EFI grubenv known issue. Workaround for it:

1. Move the /boot/grub2/grubenv to the /boot/efi/EFI/centos/:

mv /boot/grub2/grubenv /boot/efi/EFI/centos/grubenv

2. Create a symlink to the file in the old path:

ln -s ../efi/EFI/centos/grubenv /boot/grub2/grubenv
