i can switch command line , log in , says 16.04 when ran sudo apt-get update more updates can't reach ftp servers. have nvidia graphics chip know have problems i'm bit stuck start - many different answers around. other ubuntu machine (laptop) upgraded fine , online no worries.

can me troubleshoot further or point out relevant existing answers here? thanks!

if you're network connection provided wifi, you're not online yet , fail connect updates.

as graphics card, did have nvidia's proprietary drivers installed? i've been having struggles nvidia's drivers , gt 650m , have had try bunch of different versions of drivers , combinations of settings things right. fakedad asked "nomodeset" can added kernel parameters in grub. known fix black screen @ boot. answer on how add kernel boot parameter? pretty explanation of how it.

in case need remove proprietary nivida drivers, can terminal root or recovery boot with:

apt purge -y nvidia-*

followed by

apt auto remove -y

that might @ least booting again slower nouveau drivers.
