This can be tested in an arm64 docker container running on GHA amd64 runner, it's just slower.

It makes no sense why they would organize it like this.
LOL welcome to QT, there's a lot of stuff like this at download.qt.io, unfortunately.

Well, I got this working on amd64 and arm64
master...rectalogic:aqtinstall:arm64
But then I realized it broke all versions before 6.7.0. They changed the arch name for both amd and arm I guess.
Even the currently released aqt can't install 6.7.0 on amd64:

Great question! As this is a new feature, we don’t support it yet. Clearly, this is something we should support.
Part of the problem is that aqt is set up to look for Linux architectures in https://download.qt.io/online/qtsdkrepository/linux_x64/ alone. To support this, aqt would need to be changed to look in the neighboring folder, linux_arm64, as well as the original folder. I suspect that a lot of code might need to change in order to get this working, because this assumption (that aqt only needs to check a single folder) exists in lots of places.
Perhaps an easier solution would be to change the list of host names. For example, you could use never mind, I don’t like that idea.aqt install|list-qt linux … for linux_x64 hosts, and aqt install|list-qt linux_arm64 … for the arm hosts. It’s an ugly UI, and I like it a lot less than what you’ve suggested, but the change would be a lot easier to make.
Also, testing this could be problematic because we don’t have arm64 testing environments set up anywhere.

Support for linux arm64 gh actions runners is tracked here: actions/runner-images#5631
This feature will be a lot easier to test after 5631 is implemented

From this code, at https://github.com/rectalogic/aqtinstall/blob/arm64/aqt/helper.py#L282-L288:
def os_arch_ext(os_name: str) -> str:
if os_name == "windows":
return "_x86"
elif os_name == "linux" and platform.machine() == "aarch64":
return "_arm64"
else:
return "_x64"Looks like some logic is missing. Here's some pseudocode that I think might fix the issue:
if host == "linux":
if qt_version >= Version("6.7.0"):
if flavor == "arm64":
arch = "linux_gcc_arm64"
else: # flavor == "x86"
arch = "linux_gcc_64"
else:
arch = "gcc_64"
else:
# handle mac and windowsAlso, please keep in mind that we try to give users the ability to install whatever they want, wherever they want it. You're allowed to install Mac binaries on a Windows or Linux machine, etc. I think this is to allow cross compilation. Checking that platform.machine() == "aarch64" would break that.

Hmm, so src/doc/examples are in qtsdkrepository/linux_x64/desktop/ - so will they be replicating those under qtsdkrepository/linux_arm64/desktop/ - so then we would need an arch to install src?
I think your original idea of a new host - linux and linux_arm64 (that you didn't like) might be a much simpler way to deal with this. I guess I'll wait and see how they end up organizing all this. It makes no sense why they would organize it like this.

I updated the patch to use linux_arm64 host:
master...rectalogic:aqtinstall:arm64
It seems OK, except when installing on arm64 it's missing a library.

PR #765 is another attempt at supporting this, without changing the linux host type.
