f5 big-ip access policy manager UPGRADE

Affected: >= 17.1.0 and <= 17.1.3 · >= 17.5.0 and <= 17.5.1 · >= 16.1.0 and <= 16.1.6 · 21.0.0

Fixed in: newer than 17.5.1

Safe to downgrade to: a release before 16.1.0

1. Check installed version

apt-cache policy big-ip-access-policy-manager || rpm -q big-ip-access-policy-manager || big-ip-access-policy-manager --version

2. UPGRADE to newer than 17.5.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade big-ip-access-policy-manager

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade big-ip-access-policy-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 16.1.0 (Debian / Ubuntu)

apt-cache madison big-ip-access-policy-manager sudo apt install big-ip-access-policy-manager=<VERSION_BEFORE_16.1.0> sudo apt-mark hold big-ip-access-policy-manager

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

dnf --showduplicates list big-ip-access-policy-manager sudo dnf downgrade big-ip-access-policy-manager-<VERSION_BEFORE_16.1.0> sudo dnf versionlock add big-ip-access-policy-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
