[Windows GH Actions] "Failed to locate XML data for Qt version '6.8.1'."

[AlbrechtL]

Hi,

in my latest GH Actions runs, I receive the following error. So far, I didn't change the workflow.

 Successfully installed aqtinstall-3.1.20 beautifulsoup4-4.12.3 bs4-0.0.2 certifi-2024.12.14 charset-normalizer-3.4.0 defusedxml-0.7.1 humanize-4.11.0 idna-3.10 patch-1.16 py7zr-1.0.0rc1 requests-2.32.3 semantic-version-2.10.0 soupsieve-2.6 urllib3-2.2.3

aqt list-qt windows desktop clearly shows that Qt 6.8.1 is available.

Do you have any idea what could be wrong?

It's an upstream bug in aqt 3.1.20. The fix is already merged but not released yet. In the meantime, you can try adding aqtversion: '==3.1.19' under the with: section for install-qt-action. And remove it later once aqt 3.1.21 is released.

Perfect! This workaround works. Thanks for helping!
