gnuedu gnu edu DOWNGRADE

Affected: 1.3b2

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.3b2

1. Check installed version

apt-cache policy gnu-edu || rpm -q gnu-edu || gnu-edu --version

2. No fixed release: DOWNGRADE to a release before 1.3b2 (Debian / Ubuntu)

apt-cache madison gnu-edu sudo apt install gnu-edu=<VERSION_BEFORE_1.3b2> sudo apt-mark hold gnu-edu

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

dnf --showduplicates list gnu-edu sudo dnf downgrade gnu-edu-<VERSION_BEFORE_1.3b2> sudo dnf versionlock add gnu-edu

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.
