I have tried googling for this to see if people have similar issues but found nothing.
I recently obtained a Raspberry Pi 4 (2gb), installed raspbian lite earlier today which all worked just fine, but I was really interested in setting up a 64-bit OS instead, I upgraded the kernel and was able to run/install things using chroot but since I would prefer having full 64-bit to be able to run systemd services through it, I was looking for an alternative.
I found out the Ubuntu server now has images for raspberry pi, including 64-bit ones, so I rushed over to their download page (https://ubuntu.com/download/raspberry-pi) and downloaded 18.04.4 LTS (64-bit) for the RPi 4.
Attempting to install it using the Raspberry Pi Imager tool (I previously used for the raspbian image) everything from writing/verifying seems to happen at the right time duration, but in the end it will tell me the data on the sd card does not match what was written to it.
I gave it multiple attempts, and even tried multiple images (18.04.4 LTS as well as 19.10 (both 64-bit) and 18.04 32-bit version) all of them gave me the same result.
Playing around in the RPi Imager, I noticed there are also default options in there for installing the Ubuntu server, so I attempted using that option instead, but I was unlucky again as it gave me the same result.
Looking at the Ubuntu installation page, they are using Win32DiskImager so I figured I would give that a shot. The same thing happens (it instantly fails verification in "sector 2048").
Afraid somehow the SD-card or my adapter broke in the meantime, I figured I would try writing Raspbian Lite to it once more, and success! So this means it has to be the image file right? It's a 16gb Samsung SD card if that helps.
I am clueless on how to proceed, and as I said before can't find anyone encountering similar issues
