Google Chrome not starting

I was able to fix this by deleting all files in /home/USERNAME/.config/google-chrome/ which forces Google Chrome to regenerate all configuration and profile files. You should be able to do this with a single command:

rm ~/.config/google-chrome/*

Keep in mind that this will delete all of your bookmarks and settings. So (hopefully!) you have them synced with your Google account or backup somehow.

You can change folder's owner.. it worked for me sudo chown username ~/.config/google-chrome/... Good luck.

I had the same issue when I run google-chrome from terminal,

I found that it needed a new version of NSS: Chrome 62 need NSS>=3.26. So I installed libnss3.

$google-chrome

[6999:7036:1113/200616.549496: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.
Aborted (core dumped)

sudo apt-get install --reinstall libnss3

and it started working.

I could not get Chrome to start if I downloaded the installer from Google's website. But, I found that if I used the terminal command sudo apt-get install google-chrome-stable it installed and worked.
