dell insightiq UPGRADE

Affected: >= 5.0.0 and < 6.3.0

Fixed in: 6.3.0

Safe to downgrade to: a release before 5.0.0

1. Check installed version

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

2. UPGRADE to 6.3.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade insightiq

Note

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

3. If no update is available yet, DOWNGRADE to a release before 5.0.0 (Debian / Ubuntu)

apt-cache madison insightiq sudo apt install insightiq=<VERSION_BEFORE_5.0.0> sudo apt-mark hold insightiq

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list insightiq sudo dnf downgrade insightiq-<VERSION_BEFORE_5.0.0> sudo dnf versionlock add insightiq

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.
