New Install - limits.conf or limits.d - What do I need to change?

Hello,

I’m a longtime supporter of the Ardour project and I have hardly used the software! I remember getting frustrated with the install process several times before and putting my experimentation on the back burner. Here is what I’m getting when I ./Ardour-7.3.0-x86_64.run. I want to make sure I install this correctly from the start. Can anyone let me know what I need to do to get this install going without a hitch?

System failed the quick sanity check… Looking for the cause

System does not allow realtime for the current user… Looking for a solution

!!! WARNING !!! - The current user can not execute realtime processes.
This will adversely affect audio latency.
This system has an audio group and the user is a member. If jack was
just installed, a simple log out/in may fix this.

For best results, please correct this on your system.
(Hint: check /etc/security/limits.conf or /etc/security/limits.d/)

Note that there is some evidence of a few recent Linux distros breaking these instructions, but at least check this first.

Thank you for taking the time to respond. :slightly_smiling_face: I will take a look at this solution and try it tomorrow. BTW, I am a Kali (Debian) user with full stable updates. Not sure if Debian was one of the distros breaking the instructions.
