Install Csound on Linux Mint 20

first of all, I’m a noob on linux, but I like it… I would like to try to install Csound, but in the github page

is writed:

" 1. Edit, as root, /etc/apt/sources.list and ensure that each line beginning with deb has another line below it that is identical except that deb is replaced with deb-src . Then run sudo apt-get update ."

How can I make this? This is my sources.list file:

#deb cdrom:[Linux Mint 20.2 _Uma_ - Release amd64 20210703]/ focal contrib main

# This system was installed using small removable media
# (e.g. netinst, live or single CD). The matching "deb cdrom"
# entries were disabled at the end of the installation process.
# For information about how to configure apt package sources,
# see the sources.list(5) manual.

What must I do? Cabbage requires latest version of csound…

thanks in advice

Hi @Juspu, welcome to the forum.

What happens when you run the next command, i.e, :thinking:

sudo apt-get build-dep csound

Hi Rory,

thanks for you reply… this is the terminal output:

juspu:~$ sudo apt-get build-dep csound
[sudo] password for juspu:           
Reading package lists... Done
E: You must put some 'deb-src' URIs in your sources.list

Have you modified this list before? Your Software Sources application is an interface to this list. If you open up, there should be a ‘Restore default settings’ checkbox somewhere. Can you try clicked that and seeing what happens?


No, this is a new Mint installation… What do you think I should do? Do you think it is possible to install csound? I found the “software Sources” application, but I have no idea what I need to do in there. I can share screenshots if you think it might help…
I clicked the ‘Restore default settings’ button, but the result is the same as before…

juspu:~$ sudo apt-get build-dep csound
[sudo] password for juspu:           
Reading package lists... Done
E: You must put some 'deb-src' URIs in your sources.list

I guess the answer is in the sources.list file, where it tells us why it disabled the sources. Can you enable sources in your software sources application? Maybe send a screenshot :+1:

I don’t understand anything… This is the Software Sources…

What about enabling source code repositories? have you ever run sudo apt-get update? That’s worth doing as well as it should update your sources, but I believe the software sources application does this whenever you make some changes there…

A quick google search seems to show that on Mint, the sources are written to this location /etc/apt/sources.list.d/. Can you run
ls /etc/apt/sources.list.d/ to see what’s there? I tried Mint years ago because it looks great, but then remember getting frustrated with how it does things. So I went back to Xfce Ubuntu. Being one of the most popular distros, it’s quite easy to get help with.

Hi, thanks Rory… this is the terminal output with the command

ls /etc/apt/sources.list.d/

juspu@juspu:~$ ls /etc/apt/sources.list.d/
    additional-repositories.list  cybermax-dexter-sdl2-backport-focal.list  musicbrainz-developers-stable-focal.list  savoury1-ffmpeg4-focal.list
    brave-browser-release.list    minetestdevs-stable-focal.list            official-package-repositories.list        stebbins-handbrake-releases-focal.list

what I posted in my first comment

I love Mint… if it goes, I’m happy, really. Otherwise I try to ask on the Mint forum why you can not install Csound… (from the software center it installs, but it is an old version)

Thanks again Rory

thanks again… now I try your Cabbage…

Cabbage will not run with that version of Csound, hence the need to build from source…


in the “Software Sources” page, enabling" source code repository " the output of the terminal has changed:

can I resove or do you say that it is better to change distribution?

thanks again

Did you run sudo apt-get update before trying the build-dep command?


yes, and the terminal response is wat I shared… needless to say the file sources.list I didn’t change it. But maybe it’s like you say: mint is not the right distribution for csound…

thanks again

I don’t think mint is the wrong distro for Csound, it’s just a Debian based system, so it should build fine there. But I have no experience with it apart from a short stint many years ago. Did you have any luck getting help on the Mint forums about how to set up the software sources properly?

For anyone else reading this who might be having problems installing csound v6 on Mint, I built it from source as a dependency for ToneZ synth, but had to diverge from both sets of instructions.

Step 1 from the ToneZ README instructions:

  1. Make sure to have csound v6 installed on your computer

I built csound from source following the instructions here for Ubuntu/Debian. Step 1 of the build instructions reads:

Edit, as root, /etc/apt/sources.list and ensure that each line
beginning with deb has another line below it that is identical except
that deb is replaced with deb-src. Then run sudo apt-get update.

However my sources.list in Mint is empty. I figured out you have to edit /etc/apt/sources.list.d/official-package-repositories.list instead. Then follow the rest of the instructions to build csound v6.

Now back to the ToneZ README instructions:

  1. Copy the “Retornz” folder inside your $HOME directory

Easy enough.

  1. Finally copy the .so and/or .vst3 plugin where your host can find

For myself on Mint, I had to copy the ToneZ_V2.vst3 directory to my /lib/vst3/ directory and then copy the file to /lib/lxvst/ directory.

Now everything sounds great but for some reason, the “Open”, “Folder”, and “Save” buttons seem to do nothing for me, so I have to cycle through the presets manually. If anyone knows how to fix that, feel free to let me know.

Thanks for this. I’m going to ping @Retornz and see if he picks up the scent. If not, you’ll find him on the ToneZ discord server. He’s very quick to answer questions there.
