Fixed in: no fixed release known

Safe to downgrade to: a release before 1.0

1. Check installed version

apt-cache policy travel-management-system || rpm -q travel-management-system || travel-management-system --version

2. No fixed release: DOWNGRADE to a release before 1.0 (Debian / Ubuntu)

apt-cache madison travel-management-system sudo apt install travel-management-system=<VERSION_BEFORE_1.0> sudo apt-mark hold travel-management-system

dnf --showduplicates list travel-management-system sudo dnf downgrade travel-management-system-<VERSION_BEFORE_1.0> sudo dnf versionlock add travel-management-system

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.
