Expanding SSD partition.

[Nachteule]

Ah, now I know why automagically resize did not work [1]. Seems you copied data partition (sda1) AND swap partition (sda2) to from stick to usb

So, third option:

1) stop swap: sudo swapoff -a
2) remove swap parttion, fdisk is your friend
3) make sure that initramfs is active (I suppose it is) and reboot
4) partition should be automagically resized and swap created again

[1] Resize works only if partition is at the end of the partition table
