christophe.varoqui multipath-tools DOWNGRADE

Affected: 0.4.8

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.4.8

1. Check installed version

apt-cache policy multipath-tools || rpm -q multipath-tools || multipath-tools --version

2. No fixed release: DOWNGRADE to a release before 0.4.8 (Debian / Ubuntu)

apt-cache madison multipath-tools sudo apt install multipath-tools=<VERSION_BEFORE_0.4.8> sudo apt-mark hold multipath-tools

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

dnf --showduplicates list multipath-tools sudo dnf downgrade multipath-tools-<VERSION_BEFORE_0.4.8> sudo dnf versionlock add multipath-tools
