[Trisquel-users] Re : Dos screen

I do not think I was clear: the update to the newest kernel must be done from  
an installed system, i.e., you must first install Trisquel from the command  
line interface. After rebooting (without the Live USB), you would obtain  
again a command line interface from where to update to the latest Linux-libre  
kernel: https://trisquel.info/en/wiki/update-linux-libre-kernel

One more update and it is probable you have a graphical system.
