在 Fedora 37 中我做了
sudo dnf -y update
它更新了软件包和内核。但我记得此后我没有重启系统。我刚刚把它关掉了。
第二天，启动菜单按预期显示了多个条目。我选择第一个作为最新的默认值。但后来我的屏幕变黑了，角落里有一个闪烁的光标。
我按 CTRL + ALT + Del 重新启动系统，然后这次选择第二个启动项，我可以启动到该启动项。
现在，要恢复我尝试过的最新更新更改
sudo dnf history undo 23
它产生的输出如下：

我也尝试过
sudo dnf history rollback 23
但它给了我以下输出
Transaction history is incomplete, before 25
Transaction history is incomplete, before 25

Nothing to do.
Complete!
