My htaccess was not working after Ubuntu 14.04 upgrade. I realized the issue is with Apache configuration file, because I was allowed to override the Apache configuration while upgrade. So I compared the /etc/apache2/apache2.conf with auto backup file apache2.conf.dpkg-old. So we have to do the following replace in apache2.conf file to restore the htaccess.
Replace this
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
with
AllowOverride All
Require all granted
Restart your Apache server and check!
sudo service apache2 restart
Cheers
