monkey trickle DOWNGRADE

Affected: 1.07

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.07

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.07 (Debian / Ubuntu)

apt-cache madison trickle sudo apt install trickle=<VERSION_BEFORE_1.07> sudo apt-mark hold trickle

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

dnf --showduplicates list trickle sudo dnf downgrade trickle-<VERSION_BEFORE_1.07> sudo dnf versionlock add trickle

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.
