ihedvall mdf library DOWNGRADE

Affected: 2.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.1

1. Check installed version

apt-cache policy mdf-library || rpm -q mdf-library || mdf-library --version

2. No fixed release: DOWNGRADE to a release before 2.1 (Debian / Ubuntu)

apt-cache madison mdf-library sudo apt install mdf-library=<VERSION_BEFORE_2.1> sudo apt-mark hold mdf-library

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

dnf --showduplicates list mdf-library sudo dnf downgrade mdf-library-<VERSION_BEFORE_2.1> sudo dnf versionlock add mdf-library

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.
