greenplum greenplum UPGRADE

Affected: < 5.28.6 · >= 6.0.0 and < 6.14.0

Fixed in: 5.28.6, 6.14.0

Safe to downgrade to: a release before 6.0.0

2. UPGRADE to 5.28.6 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade greenplum

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade greenplum

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 6.0.0 (Debian / Ubuntu)

apt-cache madison greenplum sudo apt install greenplum=<VERSION_BEFORE_6.0.0> sudo apt-mark hold greenplum

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

dnf --showduplicates list greenplum sudo dnf downgrade greenplum-<VERSION_BEFORE_6.0.0> sudo dnf versionlock add greenplum

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.
