nocc nocc 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 nocc || rpm -q nocc || nocc --version

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

apt-cache madison nocc sudo apt install nocc=<VERSION_BEFORE_1.0> sudo apt-mark hold nocc

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

dnf --showduplicates list nocc sudo dnf downgrade nocc-<VERSION_BEFORE_1.0> sudo dnf versionlock add nocc

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.
