WSL ubuntu 总是失败并出现“子进程 /usr/bin/dpkg 返回错误代码 (1)”错误

Question

尝试在 win10 windows 子系统中使用 ubuntu 作为 linux 终端。但如果我运行任何命令，例如sudo apt reinstall libpaper1我得到：

Setting up passwd (1:4.8.1-1ubuntu5.20.04.4) ...
/var/lib/dpkg/info/passwd.postinst: 21: getent: not found
groupadd: group 'shadow' already exists
Group ID 42 has been allocated for the shadow group.  You have either
used 42 yourself or created a shadow group with a different ID.
Please correct this problem and reconfigure with dpkg --configure passwd''.

Note that both user and group IDs in the range 0-99 are globally
allocated by the Debian project and must be the same on every Debian
system.
dpkg: error processing package passwd (--configure):
 installed passwd package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
 passwd
E: Sub-process /usr/bin/dpkg returned an error code (1)

我尝试了多个指南和 apt-get install、update、upgrade，但总是出现这个错误！
