rackspace rackspace DOWNGRADE

Affected: 2.1.5

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.1.5

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.1.5 (Debian / Ubuntu)

apt-cache madison rackspace sudo apt install rackspace=<VERSION_BEFORE_2.1.5> sudo apt-mark hold rackspace

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

dnf --showduplicates list rackspace sudo dnf downgrade rackspace-<VERSION_BEFORE_2.1.5> sudo dnf versionlock add rackspace

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.
