Is Access Server available for ARM platforms?

Yes, it is available for ARM64 platforms on supported Ubuntu operating systems.

If you see the error message "InRelease doesn't support architecture armhf" then you are trying to install on an operating system that supports only 32-bit software. If your hardware device does support ARM64, install the correct 64-bit supported operating system and try the installation again. If your device cannot run 64-bit software you cannot install Access Server on it.
