sonatype nexus repository manager UPGRADE

Affected: >= 3.0.0 and < 3.94.0

Fixed in: 3.94.0

Safe to downgrade to: a release before 3.0.0

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 3.0.0 (Debian / Ubuntu)

apt-cache madison nexus-repository-manager sudo apt install nexus-repository-manager=<VERSION_BEFORE_3.0.0> sudo apt-mark hold 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.
