magnicomp sysinfo UPGRADE

Affected: >= 10-h76 and <= 10-h81

Fixed in: newer than 10-h81

Safe to downgrade to: a release before 10-h76

1. Check installed version

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

2. UPGRADE to newer than 10-h81 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade sysinfo

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 10-h76 (Debian / Ubuntu)

apt-cache madison sysinfo sudo apt install sysinfo=<VERSION_BEFORE_10-h76> sudo apt-mark hold sysinfo

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

dnf --showduplicates list sysinfo sudo dnf downgrade sysinfo-<VERSION_BEFORE_10-h76> sudo dnf versionlock add sysinfo

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.
