x-ways software technology ag winhex DOWNGRADE

Affected: 12.05_sr-14

Fixed in: no fixed release known

Safe to downgrade to: a release before 12.05_sr-14

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 12.05_sr-14 (Debian / Ubuntu)

apt-cache madison winhex sudo apt install winhex=<VERSION_BEFORE_12.05_sr-14> sudo apt-mark hold winhex

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

dnf --showduplicates list winhex sudo dnf downgrade winhex-<VERSION_BEFORE_12.05_sr-14> sudo dnf versionlock add winhex

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.
