今天在Ubuntu中实验时，突然Samba服务器失灵了，决定卸载重新安装，使用apt-get remove 命令之后，发现原来的配置文件/etc/samba/smb.conf和其他的一些Samba相关的文件夹都存在，决定手工删除(怀疑是配置文件出了问题)。
然而在删除了Samba相关的文件夹和文件之后，使用apt-get install 重新安装Samba时突然发现根本不会重新生成配置文件。
仔细查看重新安装时的提示信息，发现有一句：
Not replacing deleted config file /etc/samba/smb.conf
这个是突破口了，查找到如下资料：
If you installed phpmyadmin in your Debian and you receive this kind of errors:
Not replacing deleted config file /etc/phpmyadmin/apache.conf
Not replacing deleted config file /etc/phpmyadmin/config.footer.inc.PHP
Not replacing deleted config file /etc/phpmyadmin/config.header.inc.php
Not replacing deleted config file /etc/phpmyadmin/config.inc.php
Not replacing deleted config file /etc/phpmyadmin/htaccess
Not replacing deleted config file /etc/phpmyadmin/apache.conf
Not replacing deleted config file /etc/phpmyadmin/config.footer.inc.php
Not replacing deleted config file /etc/phpmyadmin/config.header.inc.php
Not replacing deleted config file /etc/phpmyadmin/config.inc.php
Not replacing deleted config file /etc/phpmyadmin/htaccess
Do as follow:
apt-get remove phpmyadmin
dpkg -P phpmyadmin
apt-get install phpmyadmin
And you will see this text as output:
Creating config file /etc/phpmyadmin/apache.conf with new version
Creating config file /etc/phpmyadmin/config.footer.inc.php with new version
Creating config file /etc/phpmyadmin/config.header.inc.php with new version
Creating config file /etc/phpmyadmin/config.inc.php with new version
Creating config file /etc/phpmyadmin/htaccess with new version
于是按照先 remove，然后 dpkg -P，再重新install的顺序成功搞定。
生成了新的smb.conf

Use 'apt-get autoremove' to remove them.
将会安装下列额外的软件包：

建议安装的软件包：
bind9 bind9utils ldb-tools ntp smbldap-tools winbind heimdal-clients
下列【新】软件包将被安装：
samba samba-common samba-common-bin
