genecys genecys DOWNGRADE

Affected: 0.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.2

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.2 (Debian / Ubuntu)

apt-cache madison genecys sudo apt install genecys=<VERSION_BEFORE_0.2> sudo apt-mark hold genecys

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

dnf --showduplicates list genecys sudo dnf downgrade genecys-<VERSION_BEFORE_0.2> sudo dnf versionlock add genecys

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.
