Ubuntu LTS 22.04 服务器最小安装上缺少联机帮助页

我已经安装了 22.04 LTS Ubuntu Server 作为最小安装并安装了以下软件包：

vim man-db manpages dialog bash-completion screen

现在当我运行时man ls，ubuntu 要求我运行unminimize命令，尽管 man 包已经安装：

$ dpkg -l | egrep "man-db|manpages"
ii  isc-dhcp-common                       4.4.1-2.3ubuntu2.1                      amd64        common manpages relevant to all of the isc-dhcp packages
ii  man-db                                2.10.2-1                                amd64        tools for reading manual pages
ii  manpages                              5.10-1ubuntu1                           all          Manual pages about using a GNU/Linux system

目录/usr/share/man/man1为空：

$ ls /usr/share/man/man1
$ man -w ls
This system has been minimized by removing packages and content that are
not required on a system that users do not log into.

To restore this content, including manpages, you can run the 'unminimize'
command. You will still need to ensure the 'man-db' package is installed.

和mandb输出：

$ sudo mandb
Purging old database entries in /usr/share/man...
Processing manual pages under /usr/share/man...
Purging old database entries in /usr/share/man/id...
Processing manual pages under /usr/share/man/id...
...
Processing manual pages under /usr/local/man...
mandb: can't update index cache /var/cache/man/oldlocal/8087: No such file or directory
0 man subdirectories contained newer manual pages.
0 manual pages were added.
0 stray cats were added.
0 old database entries were purged.
$

最奇怪的是：

$ ls $(dpkg -L coreutils | grep man1/ls.1)
ls: cannot access '/usr/share/man/man1/ls.1.gz': No such file or directory

发现这个：

$ dpkg -S bin/man
man-db: /usr/bin/manpath
local diversion from: /usr/bin/man
local diversion to: /usr/bin/man.REAL
man-db: /usr/bin/man
local diversion from: /usr/bin/man
local diversion to: /usr/bin/man.REAL
man-db: /usr/bin/mandb
man-db: /usr/bin/man-recode
$ head $(which man)
#!/bin/sh
echo "This system has been minimized by removing packages and content that are"
echo "not required on a system that users do not log into."
echo ""
echo "To restore this content, including manpages, you can run the 'unminimize'"
echo "command. You will still need to ensure the 'man-db' package is installed."
$ man.REAL -w ls
No manual entry for ls

如何在不最小化 Ubuntu 的情况下解决这个问题？
