Mirrors

Our main repo server is located in Germany and contains the pacman databases and packages, matching source packages and installers. The whole content of the mirror is regularly synced to multiple mirrors across the world.

All these servers are registered with pacman under /etc/pacman.d/mirrorlist.*. The first URL in those lists is the primary mirror, all others will be used as a fallback. You can make another mirror the primary one by moving it to the top.

In case you have problems with a particular mirror please let us know by filing an issue: https://github.com/msys2/msys2.github.io/issues

You can use rsync to update your mirror using

rsync -rtlvH --delete-after --delay-updates --safe-links \
    rsync://repo.msys2.org/builds/ ./msys2

Our repository layout is compatible with Arch Linux, which means you can use the following script to sync everything more frequently and efficiently:

https://gitlab.archlinux.org/archlinux/infrastructure/-/blob/master/roles/syncrepo/files/syncrepo-template.sh

source_url='rsync://repo.msys2.org/builds/'
lastupdate_url='https://repo.msys2.org/lastupdate'
