A Samba Issue

|
最近抛弃ubuntu改用Mate版本的Mint，但是在配置Samba的时候遇到了一个很诡异的问题

问题描述

在安装好Samba之后按照如下配置配置好

6
[Public]
    path = /home/myname
    guest ok = yes
    writable = yes
    browsable = yes
    read only = no

但是发现windows并不能访问，始终说没有权限，用其他linux系统可以正常访问

问题定位

检查Log，发现多处backtrace

原来是他所依赖的库有兼容性问题，所以更新相关的库

解决
