Affected: 2.2015.7.14

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.2015.7.14

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.2015.7.14 (Debian / Ubuntu)

apt-cache madison driveagent sudo apt install driveagent=<VERSION_BEFORE_2.2015.7.14> sudo apt-mark hold driveagent

dnf --showduplicates list driveagent sudo dnf downgrade driveagent-<VERSION_BEFORE_2.2015.7.14> sudo dnf versionlock add driveagent

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.
