broadcom unified infrastructure management UPGRADE

Affected: <= 9.20 · >= 20.3.0 and <= 20.3.3 · 20.1

Fixed in: newer than 20.3.3

Safe to downgrade to: a release before 20.1

1. Check installed version

apt-cache policy unified-infrastructure-management || rpm -q unified-infrastructure-management || unified-infrastructure-management --version

2. UPGRADE to newer than 20.3.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade unified-infrastructure-management

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade unified-infrastructure-management

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 20.1 (Debian / Ubuntu)

apt-cache madison unified-infrastructure-management sudo apt install unified-infrastructure-management=<VERSION_BEFORE_20.1> sudo apt-mark hold unified-infrastructure-management

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

dnf --showduplicates list unified-infrastructure-management sudo dnf downgrade unified-infrastructure-management-<VERSION_BEFORE_20.1> sudo dnf versionlock add unified-infrastructure-management

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.
