Download and Install AlmaLinux 9.5 Beta

If you don't want to upgrade but prefer a fresh installation, follow these instructions.

AlmaLinux 9.5 Beta is now available for download, offering users a chance to test the latest features and improvements.

Available Installation ISO Images

There are three types of installation ISO images for AlmaLinux 9.5 Beta:

  1. AlmaLinux-9.5-beta-1-x86_64-boot.iso: A single network installation CD image that downloads packages over the Internet.
  2. AlmaLinux-9.5-beta-1-x86_64-minimal.iso: A minimal self-contained DVD image that allows for offline installation.
  3. AlmaLinux-9.5-beta-1-x86_64-dvd.iso: A full installation DVD image that contains most of the AlmaLinux packages.

Downloading the ISO Images

To download a suitable ISO image, you can use the following command in your terminal. Replace the filename with the desired image:

# For the boot ISO
wget https://repo.almalinux.org/almalinux/9.5-beta/isos/x86_64/AlmaLinux-9.5-beta-1-x86_64-boot.iso

# For the minimal ISO
wget https://repo.almalinux.org/almalinux/9.5-beta/isos/x86_64/AlmaLinux-9.5-beta-1-x86_64-minimal.iso

# For the full DVD ISO
wget https://repo.almalinux.org/almalinux/9.5-beta/isos/x86_64/AlmaLinux-9.5-beta-1-x86_64-dvd.iso

Importing the AlmaLinux Public Key

To ensure the integrity of the downloaded files, you should download and import the AlmaLinux public key:

wget https://repo.almalinux.org/almalinux/RPM-GPG-KEY-AlmaLinux
gpg --import RPM-GPG-KEY-AlmaLinux

Downloading and Verifying Checksums

Next, download the checksums list to verify the integrity of your downloaded ISO image:

wget https://repo.almalinux.org/almalinux/9.5-beta/isos/x86_64/CHECKSUM

Verify the checksums list to ensure it has a "Good signature":

gpg --verify CHECKSUM

You should see output similar to this:

gpg: Signature made Mon 14 Oct 2024 02:03:45 PM EDT
gpg: Good signature from "AlmaLinux OS 9 <packager@almalinux.org>" [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: BF18 AC28 7617 8908 D6E7  1267 D36C B86C B86B 3716

Verifying the Downloaded ISO Image Checksum

To verify the checksum of the downloaded ISO image, calculate its SHA256 checksum:

sha256sum AlmaLinux-9.5-beta-1-x86_64-boot.iso

Compare the output with the expected checksum from the CHECKSUM file:

cat CHECKSUM | grep -E 'SHA256.*AlmaLinux-9.5-beta-1-x86_64-boot.iso'

Ensure that the checksums match.

Now create a bootable USB bootable using Etcher or Ventoy. After creating the bootable ISO, boot your system with it and follow the instructions provided in the link below to install AlmaLinux.

The above guide is for AlmaLinux 8.4 installation, but the instructions should be similar to all newer versions.

Installation Source Configuration

If you decide to use the AlmaLinux-9.5-beta-1-x86_64-boot.iso image, you may need to provide the following URL repository as the Installation Source if the installer cannot find the closest mirror:

https://repo.almalinux.org/vault/9.5-beta/BaseOS/x86_64/kickstart/

For the minimal or DVD ISO images, no extra Installation Sources are required.

The AlmaLinux community encourages users to test the beta release and provide feedback. This feedback is important for identifying and addressing issues before the stable release. You can report any bugs you encounter on the AlmaLinux Bug Tracker.
