使用网上的教程安装google-chrome，启动时报这个错误：
[4594:4630:1021/124049.156901:FATAL:nss_util.cc(632)] NSS_VersionCheck("3.26") Failed. NSS >= 3.26 is required. Please upgrade to the latest NSS,and if you still get this error,contact your distribution maintainer.
应该是NSS的version太低，升级NSS即可：
sudo apt install --reinstall libnss3
