apache tiles DOWNGRADE

Affected: >= 2.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.0

1. Check installed version

apt-cache policy tiles || rpm -q tiles || tiles --version

2. No fixed release: DOWNGRADE to a release before 2.0 (Debian / Ubuntu)

apt-cache madison tiles sudo apt install tiles=<VERSION_BEFORE_2.0> sudo apt-mark hold tiles

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

dnf --showduplicates list tiles sudo dnf downgrade tiles-<VERSION_BEFORE_2.0> sudo dnf versionlock add tiles

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.
