intego virusbarrier DOWNGRADE

Affected: x4

Fixed in: no fixed release known

Safe to downgrade to: a release before x4

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before x4 (Debian / Ubuntu)

apt-cache madison virusbarrier sudo apt install virusbarrier=<VERSION_BEFORE_x4> sudo apt-mark hold virusbarrier

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

dnf --showduplicates list virusbarrier sudo dnf downgrade virusbarrier-<VERSION_BEFORE_x4> sudo dnf versionlock add virusbarrier

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.
