我尝试从 11.4R1.14 升级到 13.3R5.9。在升级之前，我正在验证 jinstall，但它失败并显示消息：
> request system software validate /var/tmp/jinstall-ppc-13.3R5.9-domestic-signed.tgz
...
Validating against /config/juniper.conf.gz
mgd: error: Check-out failed for Adaptive services process (/usr/sbin/spd) without details
mgd: error: configuration check-out failed
Validation failed
WARNING: Current configuration not compatible with /var/tmp/jinstall-ppc-13.3R5.9-domestic-signed.tgz
我该如何解决？我将非常感谢任何帮助
