使用sudo apt-get upgrade说明时出现错误：
dpkg: error processing libgfortran3:amd64 (--configure):
package libgfortran3:amd64 is not ready for configuration
cannot configure (current status `half-installed')
Errors were encountered while processing:
libgfortran3:amd64
E: Sub-process /usr/bin/dpkg returned an error code (1)
它似乎不会阻止安装/升级其他应用程序。我相信这个问题是由于在升级应用程序时直接关闭我的 PC 造成的。
我怎样才能解决这个问题？
每当我尝试使用 apt-get 执行任何操作时，无论是安装、删除、清除、更新还是升级，我总是遇到相同的错误。
