myoffice my office sdk UPGRADE

Affected: >= 2.2.2 and <= 2.8.0

Fixed in: newer than 2.8.0

Safe to downgrade to: a release before 2.2.2

1. Check installed version

apt-cache policy my-office-sdk || rpm -q my-office-sdk || my-office-sdk --version

2. UPGRADE to newer than 2.8.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade my-office-sdk

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade my-office-sdk

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 2.2.2 (Debian / Ubuntu)

apt-cache madison my-office-sdk sudo apt install my-office-sdk=<VERSION_BEFORE_2.2.2> sudo apt-mark hold my-office-sdk

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

dnf --showduplicates list my-office-sdk sudo dnf downgrade my-office-sdk-<VERSION_BEFORE_2.2.2> sudo dnf versionlock add my-office-sdk

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.
