After running through the Ubuntu install options, I eventually get a screen that says "Sorry, there was a problem completing the installation." I have tried, many times, with Ubuntu 24.04.x and 24.10.
I started a support request and found this: https://kb.parallels.com/130273 Apparently, installation is unstable if the VM has more than 1 CPU enabled. Changing my VM from the default to 2 CPUs to 1 CPU did indeed stabilize the VM and I was able to successfully install Ubuntu.
I'm seeing problems installing Ubuntu LTS 24.04.1 on an M4 running parallels Version 20.1.2 (55742) on macOS 15.2. The installation process crashes somewhat randomly. I captured the details of one of them where mkinitramfs received a SIGILL when invoked (see attached file). I've also seen this pop up on dmesg in an older Ubuntu LTS 18.04 installation: [ 16.861894] Bad EL0 synchronous exception detected on CPU1, code 0x76000000 -- UNRECOGNIZED EC [ 16.861902] CPU: 1 PID: 1446 Comm: code-138f619c86 Not tainted 4.15.0-197-generic #208-Ubuntu [ 16.861909] Hardware name: Parallels International GmbH.
