我认为我犯了一个大错误，试图在我的 jetson nano 上安装的 ubuntu 18.04 (arm64) 上安装错误的 libc6 包，因为现在操作系统根本无法工作了，我不知道如何解决这个问题。
root@ziomario-desktop:~/Scaricati/arm64# dpkg -i libc6_2.24-11+deb9u4_arm64.deb
dpkg: attenzione: downgrade of libc6:arm64 from version 2.27-3ubuntu1.4 to 2.24-11+deb9u4

sudo dpkg --remove-architecture armhf
cannot remove it because it is currently in use by the database
基本上我什么也做不了，而且我怀疑如果我重新启动主板，ubuntu 将无法正确重新启动。因此，我不得不让主板继续运行，直到我修复错误。当然，我不想从头开始重新安装 ubuntu。请帮助我。谢谢。

通过运行以下命令修复了该问题：
sudo dpkg -i --force-overwrite libc6_2.27-3ubuntu1.4_arm64.deb
来自手册页：
--force-overwrite: Overwrite one package's file with another's
