ledger-cli ledger DOWNGRADE

Affected: 3.1.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.1.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 3.1.1 (Debian / Ubuntu)

apt-cache madison ledger sudo apt install ledger=<VERSION_BEFORE_3.1.1> sudo apt-mark hold ledger

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

dnf --showduplicates list ledger sudo dnf downgrade ledger-<VERSION_BEFORE_3.1.1> sudo dnf versionlock add ledger

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.
