发现之前安装的网易音乐打不开了，命令行执行看到CRASH了，修复无解，http://music.163.com/#/download 找debian ubuntu的最新版本重装，看到它的版本已经从之前安装的1.0.0更新至1.1.0了。 apt常用来更新，然而purge参数不常用，这次重点记住 apt 命令的 purge 参数，查了一下和remove有区别，删除会更彻底。强迫症重度患者怎能不用？
============================================
apt命令的几个参数以下参考自 http://blog.csdn.net/get_set/article/details/51276609 命令参考是早期的apt-get的，然而参数含义不会相差太大 [ 我承认是复制粘贴，多看一下加深记忆， purge purge purge 记三遍 
] ：
apt-get的卸载相关的命令有remove/purge/autoremove/clean/autoclean等。具体来说：
apt-get purge / apt-get –purge remove
删除已安装包（不保留配置文件)。
如软件包a，依赖软件包b，则执行该命令会删除a，而且不保留配置文件
apt-get autoremove
删除为了满足依赖而安装的，但现在不再需要的软件包（包括已安装包），保留配置文件。
apt-get remove
删除已安装的软件包（保留配置文件），不会删除依赖软件包，且保留配置文件。
apt-get autoclean
APT的底层包是dpkg, 而dpkg 安装Package时, 会将 *.deb 放在 /var/cache/apt/archives/中，apt-get autoclean 只会删除 /var/cache/apt/archives/ 已经过期的deb。
apt-get clean
使用 apt-get clean 会将 /var/cache/apt/archives/的 所有 deb 删掉，可以理解为 rm /var/cache/apt/archives/*.deb。
