vtex apps-graphql DOWNGRADE

Affected: 2.x

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.x

1. Check installed version

apt-cache policy apps-graphql || rpm -q apps-graphql || apps-graphql --version

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

apt-cache madison apps-graphql sudo apt install apps-graphql=<VERSION_BEFORE_2.x> sudo apt-mark hold apps-graphql

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

dnf --showduplicates list apps-graphql sudo dnf downgrade apps-graphql-<VERSION_BEFORE_2.x> sudo dnf versionlock add apps-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.
