artsproject arts DOWNGRADE

Affected: 1.5.10

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.5.10

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.5.10 (Debian / Ubuntu)

apt-cache madison arts sudo apt install arts=<VERSION_BEFORE_1.5.10> sudo apt-mark hold arts

After downgrade

Restart the service, and keep the package held until a fixed release ships.
