dell networker UPGRADE

Affected: < 19.10.0.7 · >= 19.11 and <= 19.11.0.3

Fixed in: 19.10.0.7

Safe to downgrade to: a release before 19.11

1. Check installed version

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

2. UPGRADE to 19.10.0.7 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 19.11 (Debian / Ubuntu)

apt-cache madison networker sudo apt install networker=<VERSION_BEFORE_19.11> sudo apt-mark hold networker

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

dnf --showduplicates list networker sudo dnf downgrade networker-<VERSION_BEFORE_19.11> sudo dnf versionlock add networker

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.
