Hi Joey

Version 3.2.2 won't work on any recent distribution of Linux (and should probably not be packaged by the distros anymore)

I would suggest first of all that you remove and purge the 3.2.2 package from your system

sudo apt --purge sonic-pi

Then you'll find it reasonably simple to build version 4.6 (and above) or version 5 which is the dev version and I have built on Mint 22.2 following this documentation

https://github.com/sonic-pi-net/sonic-pi/issues/3449

Hope that helps

@samaaron Is there a way to get the Official Packagers from Debian and Ubuntu stop packaging version 3.2.2 as it is never going to work going forward ?
