something similar to what happened to me was this post Updates kill Keyboard and mouse. unfortunately I'm stuck there. I also read on a couple other threads that I should go and use recovery mode, but when i select the option from GRUB it stops at a certain point, the screen that will allow me to fix packages won't appear.

i decided to diagnose the computer, and test the RAM; so far everything seems to be going well.

but this whole thing happened when I was doing an update around 230mb's... i still havent found a solution to the frozen Keyboard and mouse (trackpad).

but if all else fails can i just reinstall Ubuntu? would that fix the issue? what else can I try?

btw, I'm not not great with coding, so if there is anything that I need to type and put correct syntax or anything please guide me through it.

I've had Ubuntu literally for 1 day, and this happens.

any suggestions would be appreciated.
