octech oempro UPGRADE

Affected: >= 4.7 and <= 4.11

Fixed in: newer than 4.11

Safe to downgrade to: a release before 4.7

1. Check installed version

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

2. UPGRADE to newer than 4.11 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade oempro

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 4.7 (Debian / Ubuntu)

apt-cache madison oempro sudo apt install oempro=<VERSION_BEFORE_4.7> sudo apt-mark hold oempro

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

dnf --showduplicates list oempro sudo dnf downgrade oempro-<VERSION_BEFORE_4.7> sudo dnf versionlock add oempro

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.
