How to Install LMMS 1.2.2 in Ubuntu:

If you prefer installing lmms music production via Ubuntu PPA, do following steps one by one:

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 commands to refresh system package cache and install the music production software:

sudo apt update

sudo apt install lmms

NOTE: lmms-vst-server is 32-bit only package. It may install along with tons of 32-bit dependency libraries. And if you added wine apt repository, it may refuse to install.


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

This is a step by step beginner guide shows how to share a folder over local network via SMB/CIFS protocol in Ubuntu 20.04 Gnome desktop.

Share a folder in Ubuntu 20.04:

1.) First open terminal by pressing Ctrl+Alt+T on keyboard. When it opens, install samba, SMB/CIFS file, print, and login server by running command:

sudo apt install samba

Type user password (no asterisk feedback) and hit Enter to continue.

2.) Open Files (Nautilus file browser) and right-click on the folder you want to share, then click on “Local Network Share” menu option.

3.) In next pop-up window, do:

  • tick “Share this folder” to enable network sharing.
  • (optional) tick “Allow others to create and delete files in this folder”
  • (optional) tick “Guess access”
  • finally click on ‘Create Share’ button

4.) Confirm write permission (if enabled) and done!

5.) If you want remote PC to type username and password to access the shared folder, open terminal (Ctrl+Alt+T) and run command:

sudo smbpasswd -a USERNAME

Note:The “USERNAME” must be an existing user in your Ubuntu. It’s ji in my case. And set a password for remote smb access only.

Before getting access from remote PC, you may check out the IP address and / or hostname by running commands:


ip -4 address

Access the share folder from remote computer:

1. To access from Windows PC, go to Start -> Run to bring up Run command window. Type either \\ip-address\ or \\hostname\

2. To access from another Ubuntu desktop, go to Files -> Other Locations, then type either smb://ip-address/SHARE_FOLDER or smb://hostname/SHARE_FOLDER

sudo dpkg --add-architecture i386

Type user password (no asterisk feedback) when it prompts and hit Enter to continue.

2.) Download and install the repository key via command:

wget -O - | sudo apt-key add -

3.) Add wine repository via command (for Ubuntu 20.04 and Linux Mint 20):

sudo apt-add-repository 'deb focal main'

NOTE: You may replace focal in the code with:

  • bionic for Ubuntu 18.04 and Linux Mint 19.x
  • eoan for Ubuntu 19.10

4.) Add PPA for the required libfaudio0 library:

For Ubuntu 18.04 and Linux Mint 19.x only, libfaudio0 library is still required to install from a third-party repository by running command:

sudo add-apt-repository ppa:cybermax-dexter/sdl2-backport

5.) Finally install Wine 5.12 via command:

sudo apt update && sudo apt install --install-recommends winehq-devel

NOTE: installing the latest development release will automatically remove the stable version (if installed).

And for the unmet dependencies issue installing 32-bit libraries, try running command:

sudo apt-get install libgnutls30:i386 libldap-2.4-2:i386 libgpg-error0:i386 libxml2:i386 libasound2-plugins:i386 libsdl2-2.0-0:i386 libfreetype6:i386 libdbus-1-3:i386 libsqlite3-0:i386
