flippy project flippy UPGRADE

Affected: >= 7.x-1.0 and <= 7.x-1.2 · 7.x-1.x dev

Fixed in: newer than 7.x-1.2

Safe to downgrade to: a release before 7.x-1.0

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 7.x-1.0 (Debian / Ubuntu)

apt-cache madison flippy sudo apt install flippy=<VERSION_BEFORE_7.x-1.0> sudo apt-mark hold flippy

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list flippy sudo dnf downgrade flippy-<VERSION_BEFORE_7.x-1.0> sudo dnf versionlock add flippy

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.
