evga precision xoc DOWNGRADE

Affected: 6.2.7

Fixed in: no fixed release known

Safe to downgrade to: a release before 6.2.7

1. Check installed version

apt-cache policy precision-xoc || rpm -q precision-xoc || precision-xoc --version

2. No fixed release: DOWNGRADE to a release before 6.2.7 (Debian / Ubuntu)

apt-cache madison precision-xoc sudo apt install precision-xoc=<VERSION_BEFORE_6.2.7> sudo apt-mark hold precision-xoc

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

dnf --showduplicates list precision-xoc sudo dnf downgrade precision-xoc-<VERSION_BEFORE_6.2.7> sudo dnf versionlock add precision-xoc

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.
