This quick tutorial shows how to install the latest LMMS music creation tool 1.2.1 in Ubuntu 18.04, Ubuntu 19.10.

LMMS 1.2.1 has been made into Ubuntu 20.04 main repositories. There are also official .appimage package and flatpak package (runs in sandbox) available for most Linux desktop.

For those prefer installing LMMS 1.2.1 native .deb via apt-get, I’ve uploaded the Ubuntu 20.04 package backports into the unofficial PPA for Ubuntu 18.04 and Ubuntu 19.10.

1.) Open terminal either by pressing Ctrl+Alt+T on keyboard, or by searching for ‘terminal’ from your system application menu. When it opens, run command:

sudo add-apt-repository ppa:ubuntuhandbook1/lmms

Type user password (no asterisk feedback) for sudo prompt and hit Enter to continue adding the PPA.

2.) Then run command to refresh system package cache and install LMMS:

sudo apt update

sudo apt install lmms

Uninstall:

To remove lmms, run command:

sudo apt remove --autoremove lmms

And remove the PPA either via Software & Updates -> Other Software or by running command:

sudo add-apt-repository --remove ppa:ubuntuhandbook1/lmms
