## How to upgrade
We've started a gradual rollout of the updated `cloudlinux-release` package that brings necessary repo updates for 8.5.

Please, 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

2. Make sure that `/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

::: warning
If there are more repositories found, then you might have edited this file before. That means it wasn't updated. Check if `/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

:::
3. Import AlmaLinux GPG key (or accept it later during the `dnf update` step)

# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-AlmaLinux

4. Clean dnf cache

# dnf clean all

5. Make sure your system has the 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

6. Now, your system is ready for the update.

# dnf update

Review dnf output and accept the update.
::: warning
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
