Black screen with errors '[FAILED]' after attempting to install Balena Etcher

Black Screen of Errors

Running Ubuntu from USB, Process of trying to install Balena Etcher:

sudo apt-get dist-upgrade
sudo apt-get update

Then run the

sudo apt-get install balena-etcher-electron

To receive a 'unmet dependencies’ error which recommended then to run:

sudo apt --fix-broken install 

This returned a write error bc no space left on device, so I removed some unused files and cleared the trash and tried again,

sudo apt-get install balena-etcher-electron

But during this process the screen turns to what you see in the image at the top of this post:

[FAILED] Failed to start Avahi mDNS/DNS-SD Stack.
[FAILED] Failed to start Authorization Manager.
[FAILED] Failed to start Thermal Deamon Service.
[FAILED] Failed to start GNOME Display Manager.
[FAILED] Failed to start Thermal Deamon Service.
[FAILED] Failed to start Thermal Deamon Service.

The screen is unresponsive to any keyboard commands. Is it safe to force reboot? Can anyone help me understand how I came to this issue?
