ENABLE HOTSPOT IN UBUNTU

I tried a lot to enable hotspot through the GUI of Network Manager but it never happened. It created a hotspot but always the created hotspot didn't even appear in my android phone. Sometimes it is a problem in Ubuntu14.04. Same user interface worked for enabling hotspot in 13.10.Here are the steps that will guide you to enable hotspot and connect with other devices.You need to add a repository online, so make sure that you are using internet 

tech@jhola:~$ sudo add-apt-repository ppa:nilarimogard/webupd8 Update the whole list of repositories 

tech@jhola:~$sudo apt-get update                                        Adding the repository  adds ap-hotspot to the list, Now install ap-hotspot

tech@jhola:~$sudo apt-get install ap-hotspot                         ap-hotspot is now installed. Better open,configure  and start the hotspot service

tech@jhola:~$sudo ap-hotspot
tech@jhola:~$sudo ap-hotspot configure
tech@jhola:~$ sudo ap-hotspot start

After HOTSPOT is created

In case you want to see the devices that are connected to your hotspot use this command

tech@jhola:~$ arp -a

I tried it in 14.04, give it a try in other distributions, hope it works. Enjoy the Linux Tips.Keep sharing with us , at the end idea of Linux is all about sharing and learning.
