Fix NSS version not match when update Chrome in Ubuntu

If youre using ubuntu 14.04 then go to terminal

sudo apt-get install libnss3sudo apt-get update

if you have google chrome installed then run it

google-chrome

or install it again

I fixed this issue by updating the libnss3. please follow the following steps for quick fixing.

1. Open 'Software Updater', then click on 'settings' button
2. Tick 'important Security Updates (xenial-security) then close. It will update the cache.
3. Open terminal and the run the command 'sudo apt-get install libnss3'

Now you can open google-chrome. it is worked for me.

Ubuntu 16.04 LTS

Just had the same problem on Ubuntu 14.04. Solved it by running:

sudo apt-get updatesudo apt-get install --only-upgrade libnss3

Explanation: libnss3 is available on Ubuntu 14.04 in 2 versions (see https://packages.ubuntu.com/search?suite=trusty&arch=any&searchon=names&keywords=libnss3) . I don't really understand the difference between [ports] and [security], but with sudo apt-get upgrade I only got the 3.15 version of libnss3 installed. With the commands above I finally got the 3.28 version installed, which satisfies Chrome's requirements of a libnss3 >= 3.26. Chrome now starts correctly.
