ARM64/AARCH64 is a completely different processor from AMD64 (aka x86_64). The
ARM processor family is completely unrelated to the x86 family -- the AMD64 is
AMD's 64-bit extension of the Intel x86, which Intel adopted and calls x86_64.
My guess is that the AMD64 ISOs for 21.04 have not been spun up yet. Isn't it
a bit early for the 21.04 release anyway? Maybe the 21.04 ARM64/AARCH64 are
some sort of early (Alpha? Beta?) release? Given that the ARM chips are the
chips in embeded Linux / Internet of things / appliance and often have various
sorts of bleeding edge hardware, including all sorts of SOC "goodies" (on
"chip" I/O features: UARTS, CAN, SPI, I2C, PWM, GPIO, CSI, etc.) it is not
really suprising that an early release is available.
