openharmony openharmony UPGRADE

Affected: >= 3.1 and <= 3.1.2

Fixed in: newer than 3.1.2

Safe to downgrade to: a release before 3.1

1. Check installed version

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

2. UPGRADE to newer than 3.1.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade openharmony

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 3.1 (Debian / Ubuntu)

apt-cache madison openharmony sudo apt install openharmony=<VERSION_BEFORE_3.1> sudo apt-mark hold openharmony

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

dnf --showduplicates list openharmony sudo dnf downgrade openharmony-<VERSION_BEFORE_3.1> sudo dnf versionlock add openharmony

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.
