I downloaded an ISO of Ubuntu 24 but installation failed as an upgrade to Ubuntu 22 and installation failed as a new install. The installation froze on the screen titled "Develop with the best of open source" and I could not proceed and could not start the VM. Ubuntu 24.04 uses the Linux 6.8 kernel. I have Parallels v19.3.0
I installed Ubuntu Server Arm 24.04 first, and then installed ubuntu-desktop. No problems of any kind, including Tools. Parallels Pro 19.3.0
You can resolve the Ubuntu 24 ISO installation issue on Parallels v19.3.0, by considering these steps you can do it: Check Compatibility: Ensure Parallels supports Ubuntu 24.04 and the Linux 6.8 kernel. Try Alternative Method: Install Ubuntu Server first, then add the desktop environment. I hope this will help you to solve this problem.
