lonelycoder vmir DOWNGRADE

Affected: 2018-08-28

Fixed in: no fixed release known

Safe to downgrade to: a release before 2018-08-28

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2018-08-28 (Debian / Ubuntu)

apt-cache madison vmir sudo apt install vmir=<VERSION_BEFORE_2018-08-28> sudo apt-mark hold vmir

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

dnf --showduplicates list vmir sudo dnf downgrade vmir-<VERSION_BEFORE_2018-08-28> sudo dnf versionlock add vmir

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.
