您将看到 ClamAV 操作运行良好，因此我按了几次CTRL+ ，尽管这对正在运行的 ClamAV Freshclam 更新程序没有影响。但是稍后（正如您将在最后看到的），它说操作在完成之前被中断了。C
我尝试按照通常建议的方式运行sudo dpkg --configure -a，sudo apt-get install -f但是这两个命令都没有返回任何错误，也不认为还有什么需要做的。sudo apt-get dist-upgrade再次运行时也没有错误，尽管没有新的软件包需要安装。
但我还是感到不安，我应该做些什么吗？我正在运行带有 GNOME 3.20 的 Ubuntu GNOME 16.04.1，我是否应该重新安装它在那里升级的所有软件包，或者我可以检查还需要做什么吗？
