How To Fix w_scan: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu w_scan is provided by w-scan package.

w-scan is:

w_scan scans for DVB-S/S2, DVB-T, DVB-C and ATSC channels and creates a channels.conf, that can be used directly by the Linux Video Disc Recorder VDR. It is also possible to output channels in a format readable by the czap/tzap tools provided by linuxtv-dvb-zap, xine, totem, kaffeine or me-tv.

Unlike the scan utility in linuxtv-dvb-apps, there is no need to specify an initial transponder and w_scan automatically detects the DVB or ATSC card to be used.

To fix this problem, we can install more using the command below.

sudo apt-get -y install w-scan

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install w-scan.

sudo apt -y install w-scan

Or if you have aptitude installed you can use the following command.

sudo aptitude install w-scan
