truecrypt project truecrypt DOWNGRADE

Affected: 7.1 a

Fixed in: no fixed release known

Safe to downgrade to: a release before 7.1

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 7.1 (Debian / Ubuntu)

apt-cache madison truecrypt sudo apt install truecrypt=<VERSION_BEFORE_7.1> sudo apt-mark hold truecrypt

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

dnf --showduplicates list truecrypt sudo dnf downgrade truecrypt-<VERSION_BEFORE_7.1> sudo dnf versionlock add truecrypt

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.
