cisco intersight device connector UPGRADE

Affected: >= 4.3.0 and <= 7.5.0

Fixed in: newer than 7.5.0

Safe to downgrade to: a release before 4.3.0

1. Check installed version

apt-cache policy intersight-device-connector || rpm -q intersight-device-connector || intersight-device-connector --version

2. UPGRADE to newer than 7.5.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade intersight-device-connector

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade intersight-device-connector

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 4.3.0 (Debian / Ubuntu)

apt-cache madison intersight-device-connector sudo apt install intersight-device-connector=<VERSION_BEFORE_4.3.0> sudo apt-mark hold intersight-device-connector

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

dnf --showduplicates list intersight-device-connector sudo dnf downgrade intersight-device-connector-<VERSION_BEFORE_4.3.0> sudo dnf versionlock add intersight-device-connector

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.
