simple task scheduling system project simple task scheduling system DOWNGRADE

Affected: 1.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.0

1. Check installed version

apt-cache policy simple-task-scheduling-system || rpm -q simple-task-scheduling-system || simple-task-scheduling-system --version

2. No fixed release: DOWNGRADE to a release before 1.0 (Debian / Ubuntu)

apt-cache madison simple-task-scheduling-system sudo apt install simple-task-scheduling-system=<VERSION_BEFORE_1.0> sudo apt-mark hold simple-task-scheduling-system

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

dnf --showduplicates list simple-task-scheduling-system sudo dnf downgrade simple-task-scheduling-system-<VERSION_BEFORE_1.0> sudo dnf versionlock add simple-task-scheduling-system
