ubuntu 安装wireshark，并解决Lua: Error during loading问题

安装wireshark
sudo apt install wireshark，在安装过程中有个是否allowing non-root users to capture packets选项，默认否，直接回车即可。 The installation method can be changed any time by running: sudo dpkg-reconfigure wireshark-common.
按照上个命令的提示安装SNMP MIBs.

安装一切顺利，启动遇到了麻烦：
sudo wrieshark

解决：终端运行sudo gedit /usr/share/wireshark/init.lua，倒数第二行修改为：
–dofile(DATA_DIR..”console.lua”)
