daniel mealha cabrita ziproxy DOWNGRADE

Affected: 3.1.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.1.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 3.1.0 (Debian / Ubuntu)

apt-cache madison ziproxy sudo apt install ziproxy=<VERSION_BEFORE_3.1.0> sudo apt-mark hold ziproxy

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

dnf --showduplicates list ziproxy sudo dnf downgrade ziproxy-<VERSION_BEFORE_3.1.0> sudo dnf versionlock add ziproxy

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.
