umanni human resources DOWNGRADE

Affected: 1.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.0

1. Check installed version

apt-cache policy human-resources || rpm -q human-resources || human-resources --version

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

apt-cache madison human-resources sudo apt install human-resources=<VERSION_BEFORE_1.0> sudo apt-mark hold human-resources

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

dnf --showduplicates list human-resources sudo dnf downgrade human-resources-<VERSION_BEFORE_1.0> sudo dnf versionlock add human-resources

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.
