STEPS TO REPRODUCE 1. install qtcreator from kde neon packages 2. run qtcreator 3. clang parser not working OBSERVED RESULT Should see similar errors: 2020-10-25T03:16:38 Clang Code Model: Error: The clangbackend executable "/usr/libexec/qtcreator/clangbackend" does not exist. EXPECTED RESULT Clang parsing/backend working.

Should we expect this issue to be fixed in the near future? It would also be good to update QtCreator to the latest version.
Yes. this is quite annoying.
Bugs in 3rd party applications should be reported to the developers of the app, unless you suspect that the problem is a packaging issue--however 3rd-party apps from the package manager are no longer formally supported in Neon (and they never really were, really); the supported method of getting 3rd-party apps is to use Flatpak or Snap.
Well, it _is_ a packaging issue, obviously, so why suggest that it might not be? Also, Qt Creator doesn't seem to be offered as a snap or a flatpak in discover, only as a repo package, so what gives? Given that Neon is meant to be used by developers, having a working Qt Creator is somewhat important.
Wow, it's working! Thank you!
Thank you for your bug report! However this bug report was created/provided previous to 01/01/2023 and also has not received any updates since before 01/01/2025. Unfortunately KDE neon no longer provides updates for anything older than noble 24.04 based edition's. Please upgrade to KDE neon noble and if you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report. Thanks for understanding!
