我正在尝试从 20.04.2 升级。我收到此错误：
user@user:~$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
linux-image-generic : Depends: linux-modules-extra-5.4.0-81-generic but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
运行 apt --fix-broken install 时出现此错误：

我正在尝试升级以解决此问题，因为在我升级之前没有人会建议：浏览器和其他窗口导致 Ubuntu 20.04.2 LTS 崩溃
答案1
问题是：

其余一切都是由于您的损坏包裹造成的连锁反应。
修复过程分为两个步骤：
手动删除损坏的包。
软件包存储在 /var/cache/apt/archives 中。
您知道包名称。它就在您的输出中。
例子：
sudo rm /var/cache/apt/archives/linux-modules-extra-5.4.0-81-generic_5.4.0-81.91_amd64.deb让 apt 重新下载包
例子：
sudo apt-get upgrade
