intel advisor UPGRADE
Affected: < 2023.2
Fixed in: 2023.2
Safe to downgrade to: no unaffected older release
1. Check installed version
apt-cache policy advisor || rpm -q advisor || advisor --version
2. UPGRADE to 2023.2 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade advisor
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade advisor
Note
Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.
intel cluster checker DOWNGRADE
Affected: 2021.7.3
Fixed in: no fixed release known
Safe to downgrade to: a release before 2021.7.3
1. Check installed version
apt-cache policy cluster-checker || rpm -q cluster-checker || cluster-checker --version
2. No fixed release: DOWNGRADE to a release before 2021.7.3 (Debian / Ubuntu)
apt-cache madison cluster-checker
sudo apt install cluster-checker=<VERSION_BEFORE_2021.7.3>
sudo apt-mark hold cluster-checker
2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)
