apt-cache policy ec-cube || rpm -q ec-cube || ec-cube --version

2. UPGRADE to 4.2.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade ec-cube

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ec-cube

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 3.0.0 (Debian / Ubuntu)

apt-cache madison ec-cube sudo apt install ec-cube=<VERSION_BEFORE_3.0.0> sudo apt-mark hold ec-cube

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list ec-cube sudo dnf downgrade ec-cube-<VERSION_BEFORE_3.0.0> sudo dnf versionlock add ec-cube

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.
