2. Remove the current XRT and shell versions.
$ sudo yum remove xrt
3. Cold reboot the system.
4. Follow the installaon procedures outlined in Chapter 4: Installing the Deployment Soware.
It is not recommended to downgrade to a beta version. However, if you must downgrade to a
beta package, it is necessary to rst factory reset all the U50 cards installed on the system.
Downgrading to a beta package without rst factory reseng all the U50 cards installed on the
system can result in unexpected behavior. For beta package installaon, follow the installaon
steps in version 1.4 of the Alveo U50 Data Center Accelerator Card Installaon Guide (UG1370).

To list the currently installed XRT package, run the following command:
$ apt list -–installed | grep xrt
