ABOUT ArchEX 2026 Build 260106
I’ve made a new extra version of ArchEX with KDE Plasma 6.5.4-1 – latest version released 251209. Plasma is made to stay out of the way as it helps you get things done. But under its light and intuitive surface, it’s a powerhouse. So you’re free to choose ways of usage right as you need them and when you need them. This ArchEX version uses kernel 6.18.2-arch2-1. ArchEX can very easy be installed to hard drive (if you want) with Calamares Installer version 3.4.0 (latest). Installed (by me) from source.

Replacement
This ArchEX version replaces version 250507, 241124, 240509 and 240106.

How To dual boot, triple boot or multi boot Linux with Windows in a simple way and be happy
Before installing ArchEX or any other Linux system my general installation instructions may be of interest.

LOG IN to KDE Plasma
Boot up the 260106 Live System and log in from SDDM to the KDE Plasma 6.5.4-1 Desktop. When the boot process is ready you will end up at SDDM’s login screen. Login as user user with password live. You can also log in as root from SDDM.  The password for root is root.  You will also need the root password for some apps to run. Otherwise you can always use Sudo (to become root).

Wayland
Some people think that using Wayland in a Linux System is very important. Wayland is said to be the modern, simpler, more secure replacement for the aging X11 display server, offering better performance. ArchEX KDE uses Wayland instead of the X11 display server.

Program Management in Arch Linux
Arch Linux uses a proprietary system called Pacman. It is similar to that found in CRUX Linux. Read about Pacman.
You can also read all the documentation on Arch Linux. Six commands are basically the only ones you need to use:
1) pacman -Sy (update the packages database)
2) pacman -Syu (upgrading the whole system)
3) pacman -S MyUsefulProgram (the package installation command)
4) pacman -S ‐‐overwrite MyUsefulProgram (in case you get an error about “conflicting packages”)
5) pacman -R MyBadProgram (remove a package)
Very simple!
6) pacman -Scc (clean pacman cache)

Note: You can also use Yay – see below.

Errors about archlinux-keyring
If you get errors about keys (for example key A634567E8t6574 could not be looked up remotely) when trying to upgrade your system you shall run the following four commands as root:
rm -R /etc/pacman.d/gnupg/
rm -R /root/.gnupg/
gpg ‐‐refresh-keys
pacman-key ‐‐init && pacman-key ‐‐populate archlinux
pacman-key ‐‐refresh-keys
If that don’t work you can try this approach:
pacman -Sy archlinux-keyring
pacman-key ‐‐populate archlinux
pacman-key ‐‐refresh-keys
pacman -Sy
pacman -Syu

Yay – Yet Another Yogurt – An AUR Helper
If you want to install certain special packages for example Google Chrome and Spotify you can/must install Yay. Study this tutorial about how to install and use Yay – Yet Another Yogurt – An AUR Helper Written in Go.  If you want to install new packages through Yay you’ll have to run the command su user before yay -S MyNeededProgram. That is if you’re not logged in as the ordinary user user. (You can’t run Yay as root). Yay is pre-installed in ArchEX Build 260106.

UEFI/non-UEFI computers
ArchEX Build 260106 is now also for UEFI computers. I.e. before you can run ArchEX live you don’t have to go into BIOS and change Boot Mode to Legacy Support.

LANGUAGE
The default locale/language is English. While installing ArchEX to hard drive using Calamares (ArchEX Installer), you can change the default locale to Swedish or any other language. After the installation all apps will be in your chosen language.

IMPORTANT NOTE: After a hard drive installation you should immediately upgrade the kernel to 6.18.3-arch1-1. I.e. reinstall the kernel. That is done with the command sudo pacman -S linux. Watch this screenshot. I could (for some unknown reason) not make ArchEX work LIVE with kernel 6.18.3-arch1-1.

Samba connections
You can connect to your Windows computers in your Home Network through Samba and PCManFM. Watch this screenshot…

Rolling distribution
Arch Linux/ArchEX are rolling distributions, which implies that once you have installed the system on the hard drive there is no need for re-installations (which otherwise is common in the Linux world).

WHO should run Arch Linux?
My answer: The system fits the “advanced” Linux user/enthusiast, who would be willing to run an occasional command from time to time.

BENEFITS of ArchEX/Arch Linux
“Cutting Edge”-software and speed. You will for example always run the latest kernel if you upgrade ArchEX/Arch (for example) every month.

RaspArch Build 260111 for Raspberry Pi 5
RaspArch is a “ready-to-go” ARM (aarch64/arm64) system. It can only run on a Raspberry Pi 5 computer.  All included packages have been updated to the latest version as of 260111. The Desktop Environment is LXQt 2.3.

A member on RaspEX wrote this about an old version of RaspArch: I’ve used Slackware, Debian, Gentoo, Ubuntu & Arch. I prefer Arch. Ubuntu is easier to install, Arch is easier to keep up to date. You do not go through big, painful, changes every year instead you just update, once in a while, make changes if instructed. Arch has most of the benefits of Gentoo without the pain of recompiling _everything_. When you do need to build a package in Arch its painless especially if you use one of the tools that support AUR (I like Yaourt). Arch avoids the politics of Debian and Ubuntu and delivers a great Linux distribution. RaspArch now brings these advantages to the Pi 3.
