tintin\+\+ project tintin\+\+ DOWNGRADE

Affected: 2.01.6

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.01.6

1. Check installed version

apt-cache policy tintin++ || rpm -q tintin++ || tintin++ --version

2. No fixed release: DOWNGRADE to a release before 2.01.6 (Debian / Ubuntu)

apt-cache madison tintin++ sudo apt install tintin++=<VERSION_BEFORE_2.01.6> sudo apt-mark hold tintin++

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

dnf --showduplicates list tintin++ sudo dnf downgrade tintin++-<VERSION_BEFORE_2.01.6> sudo dnf versionlock add tintin++

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.
