apt apt-webshop-system DOWNGRADE

Affected: 3.0 · 4.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 3.0 (Debian / Ubuntu)

apt-cache madison apt-webshop-system sudo apt install apt-webshop-system=<VERSION_BEFORE_3.0> sudo apt-mark hold apt-webshop-system

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

dnf --showduplicates list apt-webshop-system sudo dnf downgrade apt-webshop-system-<VERSION_BEFORE_3.0> sudo dnf versionlock add apt-webshop-system

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.
