In an effort to increase performance on Linux platforms, our engineers have been working on moving Roon from its current Mono runtime environment to Microsoft’s .NET runtime. These changes should result in performance improvements for anyone using a Linux Core.
These improvements will require new dependencies on your system, so it’s important that you prepare your Core before the update is released.
You can also sign up below if you’d like to beta test these changes once you’ve ensured your system meets the new requirements.
Note: No action is needed for Cores running on Roon OS devices, including Nucleus and ROCK. They already use Microsoft’s .NET runtime.
With this change comes some updated dependency requirements for Roon to work. The most common problem we’ve found is that
libicu needs to be installed, so we recommend installing this ahead of the release.
For Ubuntu 20.x the command to do this is:
apt-get update && sudo apt-get install libicu66
For other systems, the name for
libicu and the specific package manager might be different. To find the .NET dependencies you need, click on the version number of your Linux distribution in this Microsoft article and scroll down to Dependencies.
So far our QA team has tested these improvements successfully with the following Linux distributions:
- Ubuntu 20.04
- Debian 10
- CentOS 7 and 8
Other variants of Linux may require additional changes to ensure that all dependencies are met.
If you’re running Roon Server on a supported NAS device, just follow the instructions below.
No action required.
A new Roon package will be available in the QNAP store soon. Once it is, take the update and you’ll be all set.
Make sure you’re updated to ADM 4.0+.
If you’re using a Core device from one of our partners that runs on Linux, you may need to get in touch with the manufacturer to confirm these dependencies have been met. We’ve reached out to all of our partners to let them know so they have time to address these dependencies before the update is released.
If your device is from one of the manufacturers below, we have confirmed that the dependencies have been met and your device is ready to go for the update.
Partners who have confirmed dependencies are met:
- Small Green Computer
If your Core’s manufacturer is not on the list and Roon is failing to start, we recommend contacting them directly if you have any issues starting Roon after the update.
We are expecting to release on November 3. If you’d like to get early access and help with our testing efforts, please consider joining the beta!
Our QA team has been testing these changes for some time, and our community of Alpha testers has also been testing for several weeks. So far our testing has been very promising, but in order to be sure that this change works across a wide range of systems, we are thrilled to announce we will be launching a beta for anyone who is interested in giving these changes a try! In order to be considered for testing, you must meet the following requirements: You are using Roon with a Linux Core machine You have installed the
libicudependency mentioned above or if you are using a Core device that runs on Linux and the dependencies have been met (please contact the manufacturer to confirm this with them directly).
You must have an active Roon license. While testing has gone well so far, this is pre-release software and there is a greater potential to experience bugs and crashes. If you’re not comfortable with this, beta might not be right for you. If you’re okay with this possibility, please sign up here (CLOSED 10/28).
Any devices running Roon OS (ROCK and Nucleus) have been using .NET runtime for some time, and so you won’t see any changes if you’re using these devices.
