Ubuntu 20.04 fails to soft-reboot after install

[AwlsomeAlex]

Describe the issue Similar to #3320 and what @ivorscott described. After the Ubuntu 20.04 LTS Desktop install completes, you're prompted to reboot. However, after pressing reboot you're left at a black screen which will remain until the virtual machine is cold powered off/rebooted. This also happens with Ubuntu Server 20.04, but this one is a blank screen with a blinking cursor.

Ubuntu 20.04 will boot fine after a cold boot, and I'm able to reboot from the installed disk. Maybe CD boot related issue?

Configuration

• UTM Version: 2.4.1
• OS Version: macOS Monterey 12.0.1
• Intel or Apple Silicon? Apple Silicon M1 Pro

Crash log UTM did not crash

I just observed the same issue with Ubuntu 21.10 ARM. The installer goes to a blank screen with blinking cursor after selecting "Reboot now". Have to close and start the VM again to get it to boot.

Yeah that's what I'm experiencing with 20.04

Same: the curser just stays blinking after "reboot Now". Virtualising 22.04 server.

Configuration

• UTM Version: 3.0.4
• OS Version: macOS Monterey 12.2
• Apple Silicon M1 Air

I have experienced this as well on all three builds. To me the issue appears to be with the USB drive not being dismounted/ejected on the soft reboot after install. Not sure if that is a bug in the ubiquity/subiquity installer scripts or with UTM. My workaround is to shutdown, edit the VM to eject the install ISO and/or reorder the USB drive after the hard drive.

Note that if you are attempting a LUKS LVM encrypted install, you may also need to redirect the passphrase prompt to the graphics console--see #3555.

I've experienced this on various QEMU emulators, both in UTM and using vanilla QEMU. I suspect it's a QEMU issue, not a UTM issue, but I'm not sure (there could be multiple things at play here).

Running into the same issue here.

• UTM 3.1.5
• ubuntu-20.04.4-live-server-arm64.iso
• Apple Silicon M1max 64gb

Same here: disabling the boot drive image fixes the issue.

After installation is finished and you have selected Reboot Now:

1. Shut down the VM
2. Either
   • Move USB Drive down OR
     
   • Delete USB Drive entirely
3. Start VM

This is the way.. hopefully this gets documented. If it's documented already somewhere, it should likely be more prominent.

This also helped in my case using: ubuntu-22.04.2-live-server-arm64.iso Thanks!
