我的设备是 EX4300。

我使用波纹管命令通过以下方式升级 JUNOS 版本：

request system software add reboot /var/tmp/jinstall-ex-4300-14.1X53-D47.3-demostic-signed.tgz

我收到以下错误：

NOTICE: Validating configuration against jinstall-ex-4300-14.1X53-D47.3-domestic-signed.tgz.
NOTICE: Use the 'no-validate' option to skip this if desired.

我也试过：

request system software add no-validate /var/tmp/junos-srxsme-10.4R7.5-domestic.tgz

还是这个错误。
