I cannot figure out what is wrong, this is what happens when I click on "Download now"

Do you have enough space on your flash drive?

 

 

Yes, I belive so. 30 GB free space.

Try doing a manual update: download latest release and manually extract all the bz* files overwriting those on the flash drive.

Hmmm... This seems to be a problem too. Is the flash drive broken?

Possibly, run chkdsk on a PC, also try a different USB port, preferably a USB 2.0 port, USB 3.0 not recommended.

chkdsk on Windows was OK, also on Mac. 

My USB drive (SanDisk Cruzer) does not support S.M.A.R.T. status, is that gonna be a problem?

 

I managed to update manually, by doing as you told me, copyin the bz* files and overwriting them, thank you!

You did not mention how much free RAM you have.    The upgrade process unzips the download into RAM before updating the USB stick, so a RAM shortage can make the upgrade fail.
