qt 5.12.9

Asked by vanny

Hello,

I'm transitioning over to Ubuntu 20.04 and am using the default version of QT 5.12.8 to build my application. However I'm running into a bug within QT that seems to be fixed in QT 5.12.9 as I can't recreate the bug there. Is there a plan to release QT 5.12.9?

Backtrace with 5.12.8:

May help. Remember to filter the PPA for your release of Ubuntu. Not all PPAs support all releases and the PPAs here come with the usual caveats of a PPA.

No, there is no plan to release QT 5.12.9 for Ubuntu 20.04 unless there is a strong demand, e.g. because of the bug that you mentioned.

Can you help with this problem?
