Arch linux time machine

This website provides a fake mirror for use in pacman that serves outdated package registries.

The intent is to allow for version-locked archlinux in a time where enshittification/ensloppification has taken a lot of working software from us.

Installation

Replace your mirror URL with the url of this site followed by /year/month/day of the desired version lock.

Example from /etc/pacman.conf:

[core]
Server = https://altm.tudbut.de/2026/01/07/$repo/os/$arch
# Include = /etc/pacman.d/mirrorlist

You may also need to turn off package signing, which is dangerous in theory. Packages are only taken from archive.archlinux.org however, meaning it's relatively safe, assuming you trust this site.

SigLevel = Never

Disclaimer

Old packages will contain vulnerabilities. The writer of this software does not care, but you might. Unlike debian, the arch linux time machine does not (can not) do backports.
