sonatype nexus repository manager UPGRADE

Affected: >= 3.88.0 and < 3.94.0

Fixed in: 3.94.0

Safe to downgrade to: a release before 3.88.0

1. Check installed version

apt-cache policy nexus-repository-manager || rpm -q nexus-repository-manager || nexus-repository-manager --version

2. UPGRADE to 3.94.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade nexus-repository-manager

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 3.88.0 (Debian / Ubuntu)

apt-cache madison nexus-repository-manager sudo apt install nexus-repository-manager=<VERSION_BEFORE_3.88.0> sudo apt-mark hold nexus-repository-manager

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

dnf --showduplicates list nexus-repository-manager sudo dnf downgrade nexus-repository-manager-<VERSION_BEFORE_3.88.0> sudo dnf versionlock add nexus-repository-manager

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.
