oxidforge oxid eshop UPGRADE

Affected: >= 6.2.0 and < 6.5.2

Fixed in: 6.5.2

Safe to downgrade to: a release before 6.2.0

1. Check installed version

apt-cache policy oxid-eshop || rpm -q oxid-eshop || oxid-eshop --version

2. UPGRADE to 6.5.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade oxid-eshop

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade oxid-eshop

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 6.2.0 (Debian / Ubuntu)

apt-cache madison oxid-eshop sudo apt install oxid-eshop=<VERSION_BEFORE_6.2.0> sudo apt-mark hold oxid-eshop

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

dnf --showduplicates list oxid-eshop sudo dnf downgrade oxid-eshop-<VERSION_BEFORE_6.2.0> sudo dnf versionlock add oxid-eshop

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.
