netalertx netalertx UPGRADE

Affected: >= 24.7.18 and < 24.10.12

Fixed in: 24.10.12

Safe to downgrade to: a release before 24.7.18

1. Check installed version

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

2. UPGRADE to 24.10.12 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade netalertx

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 24.7.18 (Debian / Ubuntu)

apt-cache madison netalertx sudo apt install netalertx=<VERSION_BEFORE_24.7.18> sudo apt-mark hold netalertx

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

dnf --showduplicates list netalertx sudo dnf downgrade netalertx-<VERSION_BEFORE_24.7.18> sudo dnf versionlock add netalertx

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.
