Fixed in: 4.0.11.0

Safe to downgrade to: a release before 4.0.6.0

1. Check installed version

apt-cache policy financial-transaction-manager || rpm -q financial-transaction-manager || financial-transaction-manager --version

2. UPGRADE to 4.0.11.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade financial-transaction-manager

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade financial-transaction-manager

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 4.0.6.0 (Debian / Ubuntu)

apt-cache madison financial-transaction-manager sudo apt install financial-transaction-manager=<VERSION_BEFORE_4.0.6.0> sudo apt-mark hold financial-transaction-manager

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

dnf --showduplicates list financial-transaction-manager sudo dnf downgrade financial-transaction-manager-<VERSION_BEFORE_4.0.6.0> sudo dnf versionlock add financial-transaction-manager

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.
