Problem with ap-hotspot

Question

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?

Answer 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.

Answer 2

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.
