oneflow oneflow DOWNGRADE

Affected: 0.9.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.9.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.9.0 (Debian / Ubuntu)

apt-cache madison oneflow sudo apt install oneflow=<VERSION_BEFORE_0.9.0> sudo apt-mark hold oneflow

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

dnf --showduplicates list oneflow sudo dnf downgrade oneflow-<VERSION_BEFORE_0.9.0> sudo dnf versionlock add oneflow

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.
