This is the message displayed in my terminal screen when I typed 

sudo ap-hotspot start

Another process is already running

Which process is running and how do I stop it?

I found this solution 

sudo rm /tmp/hotspot.pid

this will delete the process id created temporarily and no more the error is displayed. This worked in my case.

The problem may be with the recent version hostapd package that installs with ap-hotspot.

First uninstall ap-hotspot. Download old hostapd package(bug free) you can get it from

wget http://archive.ubuntu.com/ubuntu/pool/universe/w/wpa/hostapd_1.0-3ubuntu2.1_amd64.deb

To install hostpad.deb you can use gdebi package manager or simply

sudo dpkg -i hostapd_1.0-3ubuntu2.1_amd64.deb

After installation hold the package so no latest versions gets updated

   sudo apt-mark hold hostapd

Now install ap-hotspot normally.

  • Do not update the hostapd package.

  • Do we install ap-hotspot again? I did so sudo apt-get install and again configured and started ap-hotspot but again error was displayed " Another process already running... ps -ef | grep ap-hotspot this displayed algosig 19117 17645 0 23:14 pts/8 00:00:00 grep --color=auto ap-hotspot – sigdelsanjog Sep 18 '14 at 17:27
