openedx edx-enterprise UPGRADE

Affected: >= 7.0.2 and < 7.0.5

Fixed in: 7.0.5

Safe to downgrade to: a release before 7.0.2

1. Check installed version

apt-cache policy edx-enterprise || rpm -q edx-enterprise || edx-enterprise --version

2. UPGRADE to 7.0.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade edx-enterprise

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade edx-enterprise

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 7.0.2 (Debian / Ubuntu)

apt-cache madison edx-enterprise sudo apt install edx-enterprise=<VERSION_BEFORE_7.0.2> sudo apt-mark hold edx-enterprise

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

dnf --showduplicates list edx-enterprise sudo dnf downgrade edx-enterprise-<VERSION_BEFORE_7.0.2> sudo dnf versionlock add edx-enterprise

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.
