immunix immunix DOWNGRADE

Affected: 6.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 6.2

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 6.2 (Debian / Ubuntu)

apt-cache madison immunix sudo apt install immunix=<VERSION_BEFORE_6.2> sudo apt-mark hold immunix

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

dnf --showduplicates list immunix sudo dnf downgrade immunix-<VERSION_BEFORE_6.2> sudo dnf versionlock add immunix

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.

iputils iputils UPGRADE

Affected: <= 2000-10-10

Fixed in: newer than 2000-10-10

Safe to downgrade to: no unaffected older release

1. Check installed version

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

2. UPGRADE to newer than 2000-10-10 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade iputils

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade iputils

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.
