appbase streams DOWNGRADE

Affected: 2.1.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.1.2

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.1.2 (Debian / Ubuntu)

apt-cache madison streams sudo apt install streams=<VERSION_BEFORE_2.1.2> sudo apt-mark hold streams

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

dnf --showduplicates list streams sudo dnf downgrade streams-<VERSION_BEFORE_2.1.2> sudo dnf versionlock add streams

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.
