使用網上的教程安裝google-chrome，啓動時報這個錯誤：
[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.
應該是NSS的version太低，升級NSS即可：
sudo apt install --reinstall libnss3
