When I tried snap 24279, I did not force the start.
When I tried snap 24255, it did the "samba" loop about 15 times, then the screen went grey with an operable cursor. It stayed that way for over three hours until I did a hard restart with the power button.
When I retried 24279 I did a few things differently. I thought maybe I was having a repository problem, so I manually edited /etc/apt/sources.list before installing LMCE.

This list can be found in the "installing 0810 tutorial" under the internet installation instructions. This did not fix the problem, so I impatiently hit the "force start anyway" button during the wizard. I'm not actually sure what this button does, but figured it would not be there if it would damage my installation.
