# AlmaLinux 8.3 release notes
Distributed kernel version: 4.18.0-240.
# Installation instructions
There are three installation ISO images available:
AlmaLinux-8.3-x86_64-boot.iso - a single network installation CD image
that downloads packages over the Internet.
AlmaLinux-8.3-x86_64-minimal.iso - a minimal self-containing DVD image
that makes possible offline installation.
AlmaLinux-8.3-x86_64-dvd1.iso - a full installation DVD image that
contains mostly all AlmaLinux packages.
Select a mirror listed on the
mirrors.almalinux.org (opens new window) website (please,
don't use the
repo.almalinux.org host directly) and download a suitable ISO
image from the
8.3/isos/x86_64/ directory, for example:
$ wget https://mirror.interserver.net/almalinux/8.3/isos/x86_64/AlmaLinux-8.3-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/8.3/isos/x86_64/CHECKSUM # we are looking for “Good signature” $ gpg --verify CHECKSUM gpg: Signature made Fri 19 Feb 2021 03:04:44 PM MSK gpg: using RSA key 51D6647EC21AD6EA gpg: Good signature from "AlmaLinux <email@example.com>" [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-8.3-x86_64-boot.iso 08fd99fab31277ea3710bfc1ccb8a7229522af5d3987d5b062739cb0dc3b5e3e AlmaLinux-8.3-x86_64-boot.iso # compare it with expected checksum, it should be the same $ cat CHECKSUM | grep -E 'SHA256.*AlmaLinux-8.3-x86_64-boot.iso' SHA256 (AlmaLinux-8.3-x86_64-boot.iso) = 08fd99fab31277ea3710bfc1ccb8a7229522af5d3987d5b062739cb0dc3b5e3e
If you decided to use the
AlmaLinux-8.3-x86_64-boot.iso image, you will
need to provide the
8.3/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 minimal or dvd ISO images.
# Upgrade instructions
Upgrade the almalinux-release package to the 8.3-3.el8 version from the beta or rc repositories:
$ dnf clean all && dnf upgrade -y almalinux-release
the new package contains updated repository URLs so that you can just run:
$ dnf upgrade -y
to update the rest of the packages.
- The Minimal ISO now proposes to install only environments that can be installed from it (almbz#14 (opens new window)).
# Known issues
- There is no SecureBoot support in this release (almbz#3 (opens new window)). We are doing our best to have it in a stable release.
- The mirrors support implemented with help of the DNF fastestmirror plugin that is known to be a bit "quirky". We are going to switch to geo-location-based mirror selection in the stable version.
