Created attachment 164032 [details] Step 1. KDE Neon system upgrade SUMMARY *** After I install KDE Neon Unstable Edition in a virtual machine if I do a System Upgrade through Discover and a restart (as requested by the system) then the system after reboot is going to hang at the GRUB menu. The system hangs at this state whether I press ENTER to select the first option "Neon GNU/Linux" or I let the timer to reach 0. This bug affects X11 and Wayland equally. I have replicated the bug in both QEMU v4.0.0 and the latest versions of VirtualBox 7.0.x Significance/Rationale: 1) A lot of casual uses might prefer to test KDE Neon on a VM before they give it a spin on bare metal. If it does not work in a VM they might be hesitant to install it on their actual PC. 2) Some developers/testers might not have a spare PC on which to test & develop KDE. In such cases having KDE Neon work properly in a VM is vital. *** STEPS TO REPRODUCE 1. Install KDE Neon Unstable edition under QEMU v4.0.0 or Virtualbox v7.0.x 2. Do a system upgrade as per attached images 3. The system hangs in the GRUB menu as per the attached image. OBSERVED RESULT The system hangs at the GRUB menu. Even after a hard reboot/shutdown of the virtual machine it cannot continue past this stage. EXPECTED RESULT The system does not hang at the GRUB menu. It boots the operating system. SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.90.90 KDE Frameworks Version: 5.264.0 Qt Version: 6.6.0 Kernel version: 6.2.0-37-generic (64-bit) Graphics Platform: Wayland Tested in a Virtual Machine (in QEMU v4.0.0) with the following specs: Processor: 2 × Intel® Core™ i3-4150 CPU @ 3.50GHz Memory: 3.8 GiB of RAM Graphics Processor: llvmpipe Manufacturer: QEMU Product name: Standard PC (Q35 + ICH9, 2009) System version: pc-q35-6.2

can confirm this happens in qemu and virtualbox only in offline mode. normal installation in discover and then reboot no issues.
*** Bug 481056 has been marked as a duplicate of this bug. ***
Can confirm.
I can repro if VM uses BIOS, but if the VM uses UEFI, it seems to work
sudo apt purge grub-theme-breeze && sudo update-grub should also work around the problem
Should be "fixed" by https://invent.kde.org/plasma/breeze-grub/-/merge_requests/4 in 6.0 but considering I don't know why it broke and also not why the fix fixes it this probably deserves some testing. Packages will be available momentarily in neon unstable and testing.
