vmware spring integration UPGRADE

Affected: >= 6.4.0 and <= 6.4.12 · >= 6.5.0 and <= 6.5.10 · >= 7.0.0 and <= 7.0.5 · 7.1.0 · 7.1.0 milestone1 · 7.1.0 milestone2 · 7.1.0 milestone3 · 7.1.0 rc1

Fixed in: newer than 7.0.5

Safe to downgrade to: a release before 6.4.0

1. Check installed version

apt-cache policy spring-integration || rpm -q spring-integration || spring-integration --version

2. UPGRADE to newer than 7.0.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade spring-integration

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-integration

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 6.4.0 (Debian / Ubuntu)

apt-cache madison spring-integration sudo apt install spring-integration=<VERSION_BEFORE_6.4.0> sudo apt-mark hold spring-integration

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

dnf --showduplicates list spring-integration sudo dnf downgrade spring-integration-<VERSION_BEFORE_6.4.0> sudo dnf versionlock add spring-integration

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.
