vmware spring cloud gateway DOWNGRADE

Affected: 4.2.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.2.0

1. Check installed version

apt-cache policy spring-cloud-gateway || rpm -q spring-cloud-gateway || spring-cloud-gateway --version

2. No fixed release: DOWNGRADE to a release before 4.2.0 (Debian / Ubuntu)

apt-cache madison spring-cloud-gateway sudo apt install spring-cloud-gateway=<VERSION_BEFORE_4.2.0> sudo apt-mark hold spring-cloud-gateway

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

dnf --showduplicates list spring-cloud-gateway sudo dnf downgrade spring-cloud-gateway-<VERSION_BEFORE_4.2.0> sudo dnf versionlock add spring-cloud-gateway

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.
