I use Ubuntu Studio (http://ubuntustudio.org) but I added the KxStudio Repositories (https://kx.studio/Repositories) which are compatible with Ubuntu.

Some applications work and install without problems but for example, trying to install cadence removes a lot of ubuntu studio packages.

~$ sudo apt install cadence

Looks like KXStudio is not compatible with Ubuntu Studio, but there are multiple applications I need that are only present in the kxStudio Repositories.

There is a way around it without compiling myself these aplications?

For reference, this is the output of apt update:

Ubuntu Studio leader here. We cannot and do not support adding those repositories. We have a lot of people who come by and complain about broken systems by adding those repositories. Per our IRC chat bot:

KXStudio is a software repository for Debian-based operating systems for audio production. It is not supported by Ubuntu or Ubuntu Studio, and using its repo is highly discouraged as it can overwrite system and user settings.

Since those repositories are not simple PPAs, they are not easy to remove and require an entire reinstallation to remove.

Considering the advantages of using Ubuntu Studio Controls over other methods of configuring Jack, and because Carla and many other plugins are included in the Ubuntu repositories, there is no real need to add KXStudio.

If you do need plugins from the KXStudio repositories that are not already part of Ubuntu, consider downloading the individual packages directly from the website.

  • Thanks for the answer. It is strange that I am the first one to ask that on askubuntu. Jun 12, 2020 at 20:24
  • Most of the time the question gets asked on IRC, so I'm glad I have something to link to when people ask. :) Jun 12, 2020 at 20:26
