Affected: 1.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.2

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.2 (Debian / Ubuntu)

apt-cache madison tellme sudo apt install tellme=<VERSION_BEFORE_1.2> sudo apt-mark hold tellme

dnf --showduplicates list tellme sudo dnf downgrade tellme-<VERSION_BEFORE_1.2> sudo dnf versionlock add tellme

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.
