Fixed in: no fixed release known

Safe to downgrade to: a release before 0.3.991

1. Check installed version

apt-cache policy ht-editor || rpm -q ht-editor || ht-editor --version

2. No fixed release: DOWNGRADE to a release before 0.3.991 (Debian / Ubuntu)

apt-cache madison ht-editor sudo apt install ht-editor=<VERSION_BEFORE_0.3.991> sudo apt-mark hold ht-editor

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

dnf --showduplicates list ht-editor sudo dnf downgrade ht-editor-<VERSION_BEFORE_0.3.991> sudo dnf versionlock add ht-editor

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.
