atlantiswordprocessor atlantis word processor DOWNGRADE

Affected: 3.2.6

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.2.6

1. Check installed version

apt-cache policy atlantis-word-processor || rpm -q atlantis-word-processor || atlantis-word-processor --version

2. No fixed release: DOWNGRADE to a release before 3.2.6 (Debian / Ubuntu)

apt-cache madison atlantis-word-processor sudo apt install atlantis-word-processor=<VERSION_BEFORE_3.2.6> sudo apt-mark hold atlantis-word-processor

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list atlantis-word-processor sudo dnf downgrade atlantis-word-processor-<VERSION_BEFORE_3.2.6> sudo dnf versionlock add atlantis-word-processor

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
