Adding CachyOS Repository
Installing CachyOS repositories
Option 1: Automated Installation of CachyOS repositories
We’ve made it easy for you! Simply run the following commands to use our helper script that does all the work for you. 😉
Run the following commands:
-
Get archive with the script using one of the following utils:
Terminal window curl https://mirror.cachyos.org/cachyos-repo.tar.xz -o cachyos-repo.tar.xzTerminal window wget https://mirror.cachyos.org/cachyos-repo.tar.xzIf you don’t have
wget
, install it withsudo pacman -S wget
-
Extract and enter into the archive:
Terminal window tar xvf cachyos-repo.tar.xz && cd cachyos-repo -
Run the script with sudo:
Terminal window sudo ./cachyos-repo.sh
Behavior of the script
-
The script will auto-detect the CPU architecture, if the CPU has
x86-64-v4
orx86-64-v3
support, the script will automatically use the repositories which are optimized with this flag > and some other flags. -
The script will backup your old
pacman.conf
.
Option 2: Manual Installation
-
Install the cachyos keyring:
Terminal window sudo pacman-key --recv-keys F3B607488DB35A47 --keyserver keyserver.ubuntu.comsudo pacman-key --lsign-key F3B607488DB35A47 -
Install required packages:
Terminal window sudo pacman -U 'https://mirror.cachyos.org/repo/x86_64/cachyos/cachyos-keyring-20240331-1-any.pkg.tar.zst' \'https://mirror.cachyos.org/repo/x86_64/cachyos/cachyos-mirrorlist-18-1-any.pkg.tar.zst' \'https://mirror.cachyos.org/repo/x86_64/cachyos/cachyos-v3-mirrorlist-18-1-any.pkg.tar.zst' \'https://mirror.cachyos.org/repo/x86_64/cachyos/cachyos-v4-mirrorlist-6-1-any.pkg.tar.zst' \'https://mirror.cachyos.org/repo/x86_64/cachyos/pacman-6.1.0-7-x86_64.pkg.tar.zst'
Check CPU compatibility
If you want to add our repositories manually, you must check the compatibility of your CPU with CachyOS repositories.
If you are using the script above to add the CachyOS repositories, you can skip the check.
1. Check support by running the following the command
/lib/ld-linux-x86-64.so.2 --help | grep supported
2. Understanding the command output
Pay attention to the following text with brackets. (supported, searched)
- If you see
x86-64-v4 (supported, searched)
, that means the CPU is compatible and can use the x86-64-v4 instruction set. - If you see
x86-64-v4
, that means the CPU is incompatible and cannot use the x86-64-v4 instruction set.
Example of CPU compatible with the x86-64-v3 instruction set
> /lib/ld-linux-x86-64.so.2 --help | grep supported x86-64-v4 x86-64-v3 (supported, searched) x86-64-v2 (supported, searched)
3. Adding the CachyOS repositories
You need to edit pacman.conf
and add the repositories ABOVE THE EXISTING ARCHLINUX REPOS
sudo micro /etc/pacman.conf
If your CPU supports only x86-64
, then only add the [cachyos]
repository
# cachyos repos[cachyos]Include = /etc/pacman.d/cachyos-mirrorlist
If your CPU supports x86-64-v4
, then add [cachyos-v4]
, [cachyos-core-v4]
, [cachyos-extra-v4]
and [cachyos]
# cachyos repos## Only add this, if your CPU supports the x86-64-v4 architecture[cachyos-v4]Include = /etc/pacman.d/cachyos-v4-mirrorlist[cachyos-core-v4]Include = /etc/pacman.d/cachyos-v4-mirrorlist[cachyos-extra-v4]Include = /etc/pacman.d/cachyos-v4-mirrorlist[cachyos]Include = /etc/pacman.d/cachyos-mirrorlist
If your CPU supports x86-64-v3
, then add [cachyos-v3]
,[cachyos-core-v3]
,[cachyos-extra-v3]
and [cachyos]
# cachyos repos## Only add this, if your CPU supports the x86-64-v3 architecture[cachyos-v3]Include = /etc/pacman.d/cachyos-v3-mirrorlist[cachyos-core-v3]Include = /etc/pacman.d/cachyos-v3-mirrorlist[cachyos-extra-v3]Include = /etc/pacman.d/cachyos-v3-mirrorlist[cachyos]Include = /etc/pacman.d/cachyos-mirrorlist# After that the Arch Linux Repositories should follow##[core]#Include = /etc/pacman.d/mirrorlist# ...
Finally, update your system with the CachyOS packages:
sudo pacman -Syu
Enjoy your improved system speed with optimized CachyOS packages! 🎉
Debug packages
We provide a debuginfod server for easy access to debug symbols via gdb
. Set the following environment variable:
export DEBUGINFOD_URLS=https://debuginfod.cachyos.org
Debug packages are available in the following repository. Add it with the following configuration:
[cachyos-debug-v3]Server = https://debug.cachyos.org/repo/$arch_v3/$repo[cachyos-core-debug-v3]Server = https://debug.cachyos.org/repo/$arch_v3/$repo[cachyos-extra-debug-v3]Server = https://debug.cachyos.org/repo/$arch_v3/$repo
[cachyos-debug-v4]Server = https://debug.cachyos.org/repo/$arch_v4/$repo[cachyos-core-debug-v4]Server = https://debug.cachyos.org/repo/$arch_v4/$repo[cachyos-extra-debug-v4]Server = https://debug.cachyos.org/repo/$arch_v4/$repo
Or download them from the above URL manually.
Uninstalling CachyOS repositories
This can be resolved with installing the archlinux pacman first before reinstalling all packages.
sudo pacman -S core/pacman
Option 1: Automated Removal
Run these commands to remove the CachyOS repos from your system:
wget https://build.cachyos.org/cachyos-repo.tar.xztar xvf cachyos-repo.tar.xzcd cachyos-reposudo ./cachyos-repo.sh --remove
Option 2: Manual Removal
-
Backup or remove the config file at
/etc/pacman.conf
. -
Run this command:
Terminal window sudo mv /etc/pacman.conf.bak /etc/pacman.conf -
Switch to default Arch Linux packages with this command:
Terminal window sudo pacman -S core/pacmanpacman -Qqn | sudo pacman -S -sudo pacman -Syu
