I think you're right. Something's gone completely wrong.

and it goes on. i only copied a small part but the error is always the same

Under-voltage means your power adapter is not up to the task resulting in segmentation errors.
It could also be caused by a bad cable.
Need to get one with higher wattage depending connected devices etc.

Thanks for all the help. i will buy a new power supply. hopefully everything will work again.

Found below for reference:

Since your SD card may be quite corrupted, I would plan on (1) installing a completely fresh OS on the same card after formatting the card, or (2) replace the card and then put a fresh OS on the new card.

that's weird. i actually have a 3 amp power supply. but it's probably just defective.

33

yes i will completely rewrite this on a new sd card

Some adapters are good for charging but not stable enough to power Pi.
Can you exchange the cable ?
Any USB devices connected ?
