lwp\ \ UPGRADE

Affected: >= 6.04 and <= 6.06

Fixed in: newer than 6.06

Safe to downgrade to: a release before 6.04

1. Check installed version

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

2. UPGRADE to newer than 6.06 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade

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 6.04 (Debian / Ubuntu)

apt-cache madison sudo apt install =<VERSION_BEFORE_6.04> sudo apt-mark hold

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

dnf --showduplicates list sudo dnf downgrade -<VERSION_BEFORE_6.04> sudo dnf versionlock add

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.
