graphviz graphviz UPGRADE

Affected: >= 2.36.0 and < 10.0.0

Fixed in: 10.0.0

Safe to downgrade to: a release before 2.36.0

1. Check installed version

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

2. UPGRADE to 10.0.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade graphviz

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade graphviz

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 2.36.0 (Debian / Ubuntu)

apt-cache madison graphviz sudo apt install graphviz=<VERSION_BEFORE_2.36.0> sudo apt-mark hold graphviz

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

dnf --showduplicates list graphviz sudo dnf downgrade graphviz-<VERSION_BEFORE_2.36.0> sudo dnf versionlock add graphviz

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.
