Note

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

apt-cache madison graphql sudo apt install graphql=<VERSION_BEFORE_3.0.0> sudo apt-mark hold graphql

dnf --showduplicates list graphql sudo dnf downgrade graphql-<VERSION_BEFORE_3.0.0> sudo dnf versionlock add graphql

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.
