我正在按照使用终端的标准程序将我的 ubuntu 从 18.04 LTS 升级到 20.04 LTS。我写了以下命令。
sudo apt update && sudo apt upgrade
sudo do-release-upgrade -d
第二条命令下载了 Ubuntu 20.04 LTS 的软件包（下载大小约为 1.5GB）。随后，当我使用 chrome 浏览器时，开始安装软件包。系统突然重启，并卡在登录循环中，因此我不得不强制重启。现在我的系统上的 Ubuntu 20.04 软件包已损坏。以下是我运行
sudo apt-get install --fix-broken

我尝试sudo do-release-upgrade -d再次运行，但出现相同的错误，并要求我运行sudo apt-get install --fix-broken。此外，我的系统上还没有任何 Ubuntu 20.04 LTS 功能，一切都和以前一样保存此
另外，在屏幕截图中（您可能已经注意到）右上角有一个（！）错误，内容如下：
任何帮助都将不胜感激。如果有办法解决此问题，请告诉我。
答案1
对于将来遇到此类问题的人来说。
我过去常常
sudo rm -rvf /var/lib/apt/lists/*释放所有被保留的软件包，然后sudo apt-get install -f。请注意，在第二步中，根据哪些软件包具有未满足的依赖关系，您可能会删除一些非常重要的软件包，例如设置和登录。这是最重要的一步。您的系统现在有几个需要安装的软件包（因为您已经清除了损坏的软件包行）。为此，以下 3 个命令即可完成。
sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade
之后，您的计算机可能需要重新启动，然后一切都会修复。希望这对某些人有帮助！
