couchbase couchbase server UPGRADE

Affected: >= 5.0.0 and < 7.2.4

Fixed in: 7.2.4

Safe to downgrade to: a release before 5.0.0

1. Check installed version

apt-cache policy couchbase-server || rpm -q couchbase-server || couchbase-server --version

2. UPGRADE to 7.2.4 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade couchbase-server

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade couchbase-server

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 5.0.0 (Debian / Ubuntu)

apt-cache madison couchbase-server sudo apt install couchbase-server=<VERSION_BEFORE_5.0.0> sudo apt-mark hold couchbase-server

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

dnf --showduplicates list couchbase-server sudo dnf downgrade couchbase-server-<VERSION_BEFORE_5.0.0> sudo dnf versionlock add couchbase-server

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.
