How to install Kazam 1.5.3?

Kazam is available in the official Ubuntu repositories, but it's an old version (1.4) and ppa:kazam-team/unstable-series has not been updated for 16.04 (and does not include debian patches).

You can install Kazam 1.5.4 from my own ppa (it provides the debian packages up to 20.04):

sudo apt-add-repository ppa:sylvain-pineau/kazam
sudo apt-get update
sudo apt-get install kazam 

cd to /etc/apt/sources.d/ open up the kazam.list file and make sure you change repo to devel.

/etc/apt/sources.list.d# ls
kazam-team-ubuntu-unstable-series-xenial.list  kazam-team-ubuntu-unstable-   series-xenial.list.save

/etc/apt/sources.list.d# cat kazam-team-ubuntu-unstable-series-xenial.list
deb http://ppa.launchpad.net/kazam-team/unstable-series/ubuntu devel main
