[SOLVED] Qt 5.10 for pyqt in kubuntu 18.4

[hektor]

I'm using kubuntu 18.4 and I'm very happy with it!
I'm developing a tool in python3 using pyqt5. I'd need to use a QT-feature of QT 5.10 (https://www.kdab.com/new-qt-5-10-rec...terproxymodel/).
Any chance to get Qt 5.10 into my kubuntu installations ? ( I saw that KDE neon is using the same plasma version but QT 5.10). Is there a way to "steel" this from Neon?

Thanks a lot in advance!

You can download a installer for a standalone Qt (installs in a folder) from qt.io and work with that rather than alter your systemwide Qt installation.

Using Neon's Qt packages would break things that were compiled against 5.9.5 and depend on the ABI of that. https://paste.ubuntu.com/p/nqF4x6bv7v/ and I would not recommend trying that

Sometime in the not too distant future we will be looking to do builds of Qt 5.10.x (or more likely 5.11) for our PPAs, but at the moment I'm waiting for Qt guys to do the 5.9.5 -> 5.11 transition in Cosmic 18.10 to use as a base for those 18.04 builds.
I have some testing builds of 5.10.1 for development work (in our CI and test PPAs) but at the moment they have not had the rebuilds and QA required for end users, and we are likely as said to just skip straight to 5.11 anyway.

Thanks a lot for your reply!!!
Your reply probably saved me from destroying my system.
I'll look into the standalone installation or wait for it to arrive.
Thanks again
