[Bug]: Fail when installing Qt 6.11.0

[sandroandrade]

Bug description

download.qt.io changed the directory structure for Qt 6.11.0.

Qt 6.11.0 Windows desktop index currently contains these directories:

• qt6_6110_msvc2022_arm64_cross_compiled/
• qt6_6110_msvc2022_64/
• qt6_6110_mingw/
• qt6_6110_llvm_mingw/

There is no qt6_6110/ child directory there. So if aqt still assumes the older layout and asks for qt6_6110/qt6_6110/Updates.xml, checksum lookup will fail before it ever parses the XML.

Expected behavior

It should like on the correct path for Qt 6.11.0 onwards.

aqt and python version

aqtinstall(aqt) v3.3.0 on Python 3.14.3 [CPython GCC 15.2.1 20260209]

Operating System

Linux/Unix

Relevant log output

This works:
aqt list-qt windows desktop --arch 6.10.3
win64_llvm_mingw win64_mingw win64_msvc2022_64 win64_msvc2022_arm64_cross_compiled

This doesn´t work:
aqt list-qt windows desktop --arch 6.11.0

I think this has been fixed here: #1000

The fix has yet to be included in any release. I'm not sure when this is planned.

Thanks! I will be testing with pip install git+https://github.com/miurahr/aqtinstall.git@refs/pull/1000/head and trying that out.

Confirmed #1000 fixes things for me:

This should be closed as a duplicate of #1000
Edit: I actually meant #959 but I see the solution there points at #1000 so either or.

Yep, that fix does work. We're waiting for the maintainer.
