sergey oblomov iso wincmd DOWNGRADE

Affected: 1.6.10 · 1.7.3.3

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.6.10

1. Check installed version

apt-cache policy iso-wincmd || rpm -q iso-wincmd || iso-wincmd --version

2. No fixed release: DOWNGRADE to a release before 1.6.10 (Debian / Ubuntu)

apt-cache madison iso-wincmd sudo apt install iso-wincmd=<VERSION_BEFORE_1.6.10> sudo apt-mark hold iso-wincmd

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

dnf --showduplicates list iso-wincmd sudo dnf downgrade iso-wincmd-<VERSION_BEFORE_1.6.10> sudo dnf versionlock add iso-wincmd

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.
