avira free security suite DOWNGRADE

Affected: 2019

Fixed in: no fixed release known

Safe to downgrade to: a release before 2019

1. Check installed version

apt-cache policy free-security-suite || rpm -q free-security-suite || free-security-suite --version

2. No fixed release: DOWNGRADE to a release before 2019 (Debian / Ubuntu)

apt-cache madison free-security-suite sudo apt install free-security-suite=<VERSION_BEFORE_2019> sudo apt-mark hold free-security-suite

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

dnf --showduplicates list free-security-suite sudo dnf downgrade free-security-suite-<VERSION_BEFORE_2019> sudo dnf versionlock add free-security-suite

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.
