Affected: 1.2.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.2.1

1. Check installed version

apt-cache policy iptraf-ng || rpm -q iptraf-ng || iptraf-ng --version

2. No fixed release: DOWNGRADE to a release before 1.2.1 (Debian / Ubuntu)

apt-cache madison iptraf-ng sudo apt install iptraf-ng=<VERSION_BEFORE_1.2.1> sudo apt-mark hold iptraf-ng

After downgrade

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