datagrid project datagrid DOWNGRADE

Affected: 1.0.6

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.0.6

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.0.6 (Debian / Ubuntu)

apt-cache madison datagrid sudo apt install datagrid=<VERSION_BEFORE_1.0.6> sudo apt-mark hold datagrid

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list datagrid sudo dnf downgrade datagrid-<VERSION_BEFORE_1.0.6> sudo dnf versionlock add datagrid

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.
