Problem with ap-hotspot

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?

Solution 1:

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.
