twistedmatrix twistedweb DOWNGRADE

Affected: 14.0.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 14.0.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 14.0.0 (Debian / Ubuntu)

apt-cache madison twistedweb sudo apt install twistedweb=<VERSION_BEFORE_14.0.0> sudo apt-mark hold twistedweb

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list twistedweb sudo dnf downgrade twistedweb-<VERSION_BEFORE_14.0.0> sudo dnf versionlock add twistedweb

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.
