paloaltonetworks traps UPGRADE

Affected: >= 4.1 and <= 5.0.5

Fixed in: newer than 5.0.5

Safe to downgrade to: a release before 4.1

1. Check installed version

apt-cache policy traps || rpm -q traps || traps --version

2. UPGRADE to newer than 5.0.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade traps

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade traps

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 4.1 (Debian / Ubuntu)

apt-cache madison traps sudo apt install traps=<VERSION_BEFORE_4.1> sudo apt-mark hold traps

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

dnf --showduplicates list traps sudo dnf downgrade traps-<VERSION_BEFORE_4.1> sudo dnf versionlock add traps

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.
