RetroGrid Rescue

An emergency roll-back of a failed update!

Sometimes, you do an update and you really wish you could go back in time. You want to do a `dnf distro-sync` to some past repo state but you can't because you didn't mirror your own files.

That's where Retrogrid Rescue comes in.

Test the below configuration. As of this writing, AlmaLinux 9 is tested/released.

# Install the Retrogrid Release
dnf -y install https://repo.retrogrid.io/almalinux/retrogrid-release-0.1-4.el9.noarch.rpm

# Switch to RetroGrid Mirrors
dnf -y install retrogrid-almalinux-repos

# Register your host with RetroGrid (first 30 days are free!)
retrogrid-register

# Let's go "back in time" a week:
retrogrid-set-day 2026-02-17

# Do your rollback
dnf repo-sync

# Want to go back to the normal almalinux repos?
dnf -y swap retrogrid-almalinux-repos almalinux-repos --nobest --disablerepo='retrogrid*'
dnf remove retrogrid-release
