我想将我的系统从 Focal Fossa ( LTS ) 更新为 Hirsute Hippo ( Normal )，但我发现一些错误：

我如何从 Focal Fossa 更新到 Hirsute Hippo？（我获得指南来自https://www.linuxbabe.com/ubuntu/upgrade-ubuntu-20-04-20-10-to-21-04/amp）
答案1
do-release-upgrade 需要“lspci”命令。该命令可以在“pciutils”apt 包中找到
尝试安装该包：
root@localhost:~# apt install pciutils
然后再次运行 do-release-upgrade 命令（它对我有用）
root@localhost:~# do-release-upgrade
