Getting this error on Ubuntu 22.04.2 LTS, but it is aarch64. Looks like the modular CLI is available on ARM but mojo may not be.

Same here, it is fine to install modular, but fails to install mojo:

$ modular install mojo

Yes we don't support mojo on aarch64. Please stay tuned!

But I'm emulating AMD64 on aarch64 MacOS and still can't do it

the emulation through qemu or rosetta don't work with mojo. You can also read it in the thread on their Discord
