[member=7461]Edgewood[/member] - virtualbox updates is what's causing the issue for the most part. As long as these updates are not installed there will be no issues with the VM. Tested on VMWare Workstation Pro 14, VMWare Fusion and ESXi.
Also during updates I kept all original files when prompted (/etc/issue, etc/release and so on.) I installed every single update with VNC enabled and disabled, no vmware-tools installed and also no open-vm-tools installed just to make sure it was not a conflict between packages.
So, I would certainly hold those packages and wait for the next update and test again, but for now, if installed on a VMWare VM it will kill it. As I mentioned before, it seems to prevent policykit-1-gnome from launching which basically gives you a blank screen... lightdm/session cannot authenticate due to the missing authentication agent.
Code:
sudo apt-mark hold virtualbox-guest-dkms
sudo apt-mark hold virtualbox-guest-utils
sudo apt-mark hold virtualbox-guest-x11
OR
Code:
sudo apt-mark hold virtualbox-guest-dkms virtualbox-guest-utils virtualbox-guest-x11
Which of the three packages is the one actually killing it, I didn't test between those three because they pretty much depend on each other, so by default users will be prompted to install at least two of the tree packages due to their mutual dependency. I might run some tests later. And it makes sense after all because other users have reported having issues after installing virtualbox updates (here in the forum - recent days).
Another thing I noticed, is that policykit failed to autostart when the primary user is set to auto-login
during installation. It did the same for me twice, whether I installed updates or not during the installation process. virtualbox packages do not get updated during installation though, so there are two different scenarios in which we can end up with a blank screen VM or a VM that doesn't launch applications that requires administrative privileges due to the broken authentication agent.
Finally, I tested Install Updates (
https://github.com/linuxlite/litesoftwar...s-gui#L177) and in the case of these packages they are defaulting to keep the original file, so users shouldn't have had any issues because of the non-interactive install.
That's what I've found during my tests. Maybe someone else wants to try to replicate this.
