arm64 and aarch64 are supposed to be the same thing (or not?). I got my Ubuntu architecture aarch64 using
uname --m
But most binary launcher of apps are in arm64. Is there any way to run arm64 apps(binaries) on aarch64?
See Differences between arm64 and aarch64. AArch64 and arm64 are the same thing. Does executing the binary not work for you?
These are the simple steps, Please try with these steps.
dpkg --add-architecture armhf
apt-get update (ignore the missing x386 packages and hope for the best)
apt-get install libc6:armhf libstdc++6:armhf
