devellion cubecart DOWNGRADE

Affected: 3.0.15

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.0.15

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 3.0.15 (Debian / Ubuntu)

apt-cache madison cubecart sudo apt install cubecart=<VERSION_BEFORE_3.0.15> sudo apt-mark hold cubecart

dnf --showduplicates list cubecart sudo dnf downgrade cubecart-<VERSION_BEFORE_3.0.15> sudo dnf versionlock add cubecart

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.
