Wordpress update - Failing due to the checksum value

I have been trying to update the WordPress version but I'm having the nex error:

Download failed.: The checksum of the file (de7c388bf9dec3acbc05570fafdwe7ff) does not match the expected checksum value (78d806bdf71ed84e2b5e92dfb37947d2).

I can install/update plugins without errors
