vmware spring cloud config UPGRADE

Affected: >= 3.1.0 and < 3.1.14 · >= 4.1.0 and < 4.1.10 · >= 4.2.0 and < 4.2.7 · >= 4.3.0 and < 4.3.3 · >= 5.0.0 and < 5.0.3

Fixed in: 3.1.14, 4.1.10, 4.2.7, 4.3.3, 5.0.3

Safe to downgrade to: a release before 3.1.0

1. Check installed version

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

2. UPGRADE to 3.1.14 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade spring-cloud-config

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-cloud-config

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 3.1.0 (Debian / Ubuntu)

apt-cache madison spring-cloud-config sudo apt install spring-cloud-config=<VERSION_BEFORE_3.1.0> sudo apt-mark hold spring-cloud-config

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

dnf --showduplicates list spring-cloud-config sudo dnf downgrade spring-cloud-config-<VERSION_BEFORE_3.1.0> sudo dnf versionlock add spring-cloud-config

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.
