hanterm hanterm-xf DOWNGRADE

Affected: 2.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.0

1. Check installed version

apt-cache policy hanterm-xf || rpm -q hanterm-xf || hanterm-xf --version

2. No fixed release: DOWNGRADE to a release before 2.0 (Debian / Ubuntu)

apt-cache madison hanterm-xf sudo apt install hanterm-xf=<VERSION_BEFORE_2.0> sudo apt-mark hold hanterm-xf

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

dnf --showduplicates list hanterm-xf sudo dnf downgrade hanterm-xf-<VERSION_BEFORE_2.0> sudo dnf versionlock add hanterm-xf

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.
