Is qtwinextras a valid option on non-Windows systems?
As far as I can see, it's not removed in config_options.

[KerstinKeller]

No, it's not a valid option for non windows platforms, [see here] (https://doc.qt.io/qt-5/qtwinextras-index.html)

[KerstinKeller]

I just realized, default for qt package on Windows is static linkage (which is weird by itself, since default - in order to comply with LGPL - should be shared). So appending to the system libs needs to be in the section that checks for static linkage (starting line 1084)

@uilianries how can I see what went wrong?

unfortunately, with unexpected error there is no way to see log on what exactly have happened.
we're (slowly) improving the CI to turn some unexpected errors into correct (human-readable, user-friendly) error messages.

for this particular failure, it was an upload error:

Error running command `conan upload qt/5.15.2@#1e902b0406eaf5f9df71074a080224a4:3f6053cb7e2ae8a9639326c5df78e53b54511aae -r c3i_PR-6856`

perhaps, network issue
