fecmall project fecmall UPGRADE

Affected: >= 2.0.0 and <= 2.13.3

Fixed in: newer than 2.13.3

Safe to downgrade to: a release before 2.0.0

1. Check installed version

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

2. UPGRADE to newer than 2.13.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade fecmall

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade fecmall

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 2.0.0 (Debian / Ubuntu)

apt-cache madison fecmall sudo apt install fecmall=<VERSION_BEFORE_2.0.0> sudo apt-mark hold fecmall

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

dnf --showduplicates list fecmall sudo dnf downgrade fecmall-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add fecmall

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.
