Didn't you say you just upgraded to a new version of Mint, whcih was released like days ago?from Mint Linux, ... trying to get Studio One to work... and have decided to give up.
When was that version of Studio One created (ie, compiled)? Has it been created within the past couple of months, for example? Or do you have some version that's like 2 years old.
The reason I ask is because not each update to the linux OS (kernel) is 100% backward compatibile to older versions. Sometimes, if you're trying to run software that was created under an older linux version, some backward compatibility issue (usially referred to as a "regression") will come into play under a newer kernel,
If you still have a copy of your previous version of Mint, try using that. You may find that your Studio One version runs well under that, likely because that's the versions of OS libraries and support files it was created with.
You need to be judicious with updating your operating system, and applications. Try to avoid updating them separately. If you've got a brand new kernel update, hold off on upgrading it until such time as you also have recent updates of all your needed apps. Don't install today's kernel if you have an important app whose latest version was created 3 years ago (and that's all that is available). That's asking for trouble.
