Driver 20.2.0 or Later Fails to Be Rolled Back to an Earlier Version
If the system displays a message "Device_images_crl_check failed" during the rollback, perform the following operations:
- Log in to the operating environment as the root user and run the following command to uninstall the driver. The default installation path /usr/local/Ascend/driver/ is used as an example.
[root@localhost ~]# /usr/local/Ascend/driver/script/uninstall.sh
- Run the following hot reset command if the system prompts you to restart the system for the uninstallation to take effect. Skip this step if a message is displayed indicating that the uninstallation takes effect immediately.
[root@localhost ~]# reboot
- Run the following command to delete the ascend_check directory from the root path:
[root@localhost ~]# rm -rf /root/ascend_check
- Perform the rollback again.
