我正在将 Ubuntu 从 14.04 升级到 16.04。我是 Ubuntu 新手。一切都很顺利，直到最后。它下载了所有新软件包。在安装过程中。最后我得到了以下错误。
Could not install "initscripts."
然后它发出了以下消息。
Upgrade will continue, but the initscripts packages may not be working state.
Please submit a bug report.
subprocess installed post-installation script returned error exit status 1.
它给出了以下附加错误。
Could not install "plymouth."
subprocess installed post-installation script returned error exit status 1.
Could not install "cgmanager."
subprocess installed post-installation script returned error exit status 1.
Could not install "rfupdown."
subprocess installed post-installation script returned error exit status 1.
Couldn't install the upgrades.
The update has aborted. Your system should be in an unstable state.
A recovery will run now (dpkg --configure -a).
它显示版本 16.04，但只有一个选项，关机。我关机了。然后我必须通过工厂映像安装早期版本 14.04。
现在我该怎么做？
