netbox netbox UPGRADE

Affected: >= 4.1.7 and <= 4.2.1

Fixed in: newer than 4.2.1

Safe to downgrade to: a release before 4.1.7

1. Check installed version

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

2. UPGRADE to newer than 4.2.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade netbox

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 4.1.7 (Debian / Ubuntu)

apt-cache madison netbox sudo apt install netbox=<VERSION_BEFORE_4.1.7> sudo apt-mark hold netbox

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

dnf --showduplicates list netbox sudo dnf downgrade netbox-<VERSION_BEFORE_4.1.7> sudo dnf versionlock add netbox

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.
