Ubuntu 16.04自动更新

Question

根据文档 当你做

def generator_containing_discriminator_and_classifier(generator, discriminator, classifier):
   inputs = Input((IN_CH, img_cols, img_rows))
   x_generator = generator(inputs)
   merged = merge([inputs, x_generator], mode='concat', concat_axis=1)
   discriminator.trainable = False
   x_discriminator = discriminator(merged)
   classifier.trainable = False
   x_classifier = classifier(x_generator)
   model = Model(input=inputs, output=[x_generator, x_discriminator, x_classifier])
   return model

def generator_containing_discriminator(generator, discriminator):
   inputs = Input((IN_CH, img_cols, img_rows))
   x_generator = generator(inputs)
   merged = merge([inputs, x_generator], mode='concat',concat_axis=1)
   discriminator.trainable = False
   x_discriminator = discriminator(merged)
   model = Model(input=inputs, output=[x_generator,x_discriminator])
   return model

您应该看到

cd /etc/apt/apt.conf.d/
vim 50unattended-upgrades

在具有ubuntu 14.04的服务器上，这正是我所看到的，并且更新正常。

但是在具有ubuntu 16.04（vestacp）的服务器上，我得到了：

Unattended-Upgrade::Allowed-Origins {
 "${distro_id}:${distro_codename}";
 "${distro_id}:${distro_codename}-security";
 //      "${distro_id}:${distro_codename}-updates";
 //      "${distro_id}:${distro_codename}-proposed";
 //      "${distro_id}:${distro_codename}-backports";
}

我也看不到文件

Unattended-Upgrade::Allowed-Origins {
"Ubuntu xenial-security";
}

无人参与的升级已安装

我该怎么办？
