# Installation instructions
There are three installation ISO images available:
AlmaLinux-8.4-x86_64-boot.iso - a single network installation CD image
that downloads packages over the Internet.
AlmaLinux-8.4-x86_64-minimal.iso - a minimal self-containing DVD image
that makes possible offline installation.
AlmaLinux-8.4-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 (local mirrors will be a lot quicker than using repo.almalinux.org directly) and download a suitable ISO image from the 8.4/isos/x86_64/ directory, for example:
$ wget https://mirror.interserver.net/almalinux/8.4/isos/x86_64/AlmaLinux-8.4-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/isos/x86_64/CHECKSUM
# we are looking for “Good signature”
$ gpg --verify CHECKSUM
gpg: Signature made Wed 26 May 2021 08:21:40 AM UTC using RSA key ID C21AD6EA
gpg: Good signature from "AlmaLinux <packager@almalinux.org>"
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-x86_64-boot.iso
76e8f56892e6d90706b142868eec51b6b8c015ec3792f8d9e0730da93a2d1162 AlmaLinux-8.4-x86_64-boot.iso
# compare it with expected checksum, it should be the same
$ cat CHECKSUM | grep -E 'SHA256.*AlmaLinux-8.4-x86_64-boot.iso'
SHA256 (AlmaLinux-8.4-x86_64-boot.iso) = 76e8f56892e6d90706b142868eec51b6b8c015ec3792f8d9e0730da93a2d1162
If you've decided to use the AlmaLinux-8.4-x86_64-boot.iso image, you will
need to provide the 8.4/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
Just run:
$ dnf upgrade -y
to update your AlmaLinux OS 8.3 stable to 8.4.
If you’re upgrading from 8.4 beta then you should run
$ dnf upgrade -y
twice.
# 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 geo-location-based mirror selection soon.
- We don’t provide OVAL definitions for AlmaLinux updates yet so the
Ensure Software Patches InstalledOpenSCAP check will be marked asnotchecked. However, OpenSCAP is already configured for AlmaLinux OVAL sources so no configuration will be needed when definitions become available.
