I have Parallels Version 19.0.0 (54570) with a Business Edition license. According to this article, I should be able to "create a new virtual machine from the list of Free Systems and select Download Ubuntu with x86_64 emulation." There is a screenshot in the article showing the separate ubuntu in the OS list. https://kb.parallels.com/en/129871 However, I do not see this OS in the list to create a new VM. The option to add emulation to an already-created VM is also missing. Any suggestions?
