Linux Mint的network界面启动不了

最近安装了一些python库，安装之后发现系统的network界面一直启动不了。
network是可以用的，只是改不了配置。那来看看启动界面时报了什么错

进入目录, 这里存放的文件是，系统菜单启动软件的配置

cd /usr/share/applications/
ls | grep network

输出结果，network的启动配置

cinnamon-network-panel.desktop

cat一下，看看配置

$ cat  cinnamon-network-panel.desktop

[Desktop Entry]
Exec=cinnamon-settings network
Icon=cs-network
Terminal=false
Type=Application
StartupNotify=true
Categories=GTK;Settings;HardwareSettings;X-Cinnamon-Settings-Panel;
OnlyShowIn=X-Cinnamon;
X-Cinnamon-Settings-Panel=network
# Translators: those are keywords for the network control-center panel
Keywords=Network;Wireless;IP;LAN;Proxy;Internet;WiFi;
Name=Network
Comment=Network settings
X-Ubuntu-Gettext-Domain=cinnamon-control-center

上述的输出结果中，Exec是network界面启动命令。手动执行一下

$ cinnamon-settings network

嗯嗯，似乎找到问题了。

python库pillow的问题，重新安装一下就正常了

$ sudo pip install pillow

我之前安装了pillow包，可能是安装出错了，就出了这样的问题。
