# Installation instructions

There are three installation ISO images available:

AlmaLinux-8.4-beta-1-x86_64-boot.iso - a single network installation CD image that downloads packages over the Internet.

AlmaLinux-8.4-beta-1-x86_64-minimal.iso - a minimal self-containing DVD image that makes possible offline installation.

AlmaLinux-8.4-beta-1-x86_64-dvd.iso - a full installation DVD image that contains mostly all AlmaLinux packages.

The recommended way to download ISO images is using the torrent (opens new window) links. Alternatively, you can select a mirror closest to your geographic area listed on the mirrors.almalinux.org (opens new window) website. A local mirrors will be alot quicker than using repo.almalinux.org directly. Then, download a suitable ISO image from the 8.4-beta/isos/x86_64/ directory of your source, for example:

$ wget https://mirror.interserver.net/almalinux/8.4-beta/isos/x86_64/AlmaLinux-8.4-beta-1-x86_64-boot.iso

Download and import the AlmaLinux public key:

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

Download and verify a checksums list:

$ wget https://repo.almalinux.org/almalinux/8.4-beta/isos/x86_64/CHECKSUM

# we are looking for “Good signature”
$ gpg --verify CHECKSUM
  gpg: Signature made Thu Apr 29 11:34:13 2021 UTC
  gpg:                using RSA key 51D6647EC21AD6EA
  gpg: Good signature from "AlmaLinux <[email protected]>" [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: 5E9B 8F56 17B5 066C E920  57C3 488F CF7C 3ABB 34F8
       Subkey fingerprint: E53C F5EF 91CE B0AD 1812  ECB8 51D6 647E C21A D6EA

Verify the downloaded ISO image checksum:

# calculate the downloaded ISO SHA256 checksum
$ sha256sum AlmaLinux-8.4-beta-1-x86_64-boot.iso
e0e50a5db9cccfa70eaba9b4465e3e727ebed689f1a30dbbd7fcfa6046f05890  AlmaLinux-8.4-beta-1-x86_64-boot.iso

# compare it with expected checksum, it should be the same
$ cat CHECKSUM | grep -E 'SHA256.*AlmaLinux-8.4-beta-1-x86_64-boot.iso'
SHA256 (AlmaLinux-8.4-beta-1-x86_64-boot.iso) = e0e50a5db9cccfa70eaba9b4465e3e727ebed689f1a30dbbd7fcfa6046f05890

If you decide to use the AlmaLinux-8.4-beta-1-x86_64-boot.iso image, you will need to provide the 8.4-beta/BaseOS/x86_64/kickstart/ repository from the selected mirror as the Installation Source.

There are no extra Installation Sources required if you decided to go with either the minimal or DVD ISO images.

# Upgrade Instructions

Please do not use these update instructions on production machines, unless you don't mind if something breaks. 😉

Upgrade the almalinux-release package to the 8.4-1.el8 version from the beta repositories:

$ dnf install -y https://repo.almalinux.org/almalinux/almalinux-release-latest-8-beta.x86_64.rpm
$ dnf clean all

the new package contains updated repository URLs so that you can just run:

$ dnf upgrade -y

to update the rest of the packages.

# Known issues

  • The mirrors support implemented with help of the DNF fastestmirror plugin is known to be a bit "quirky". We are going to switch to geolocation-based mirror selection in the 8.4 stable version.
  • The python39-devel:3.9 module is not available in beta and will be added in stable.
