oxid-esales eshop UPGRADE

Affected: >= 6.5.0 and < 6.5.3

Fixed in: 6.5.3

Safe to downgrade to: a release before 6.5.0

1. Check installed version

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

2. UPGRADE to 6.5.3 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade 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 6.5.0 (Debian / Ubuntu)

apt-cache madison eshop sudo apt install eshop=<VERSION_BEFORE_6.5.0> sudo apt-mark hold eshop

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

dnf --showduplicates list eshop sudo dnf downgrade eshop-<VERSION_BEFORE_6.5.0> sudo dnf versionlock add 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.
