+1 on this. Shall be as trivial as adding mamba install -y pyside6. pyside2 and pyside6 coexistence shall not be an issue, as they live in pyside2/pyside6 namespace.

This will be part of the cycle 29 build.

After talking to Te-Wei, I also will upgrade the version of PySide2 from 5.13.2 to 5.15.8.

Both the newer PySide2 conda package and the PySide6 conda package require newer versions of the pyqt and pyqt-impl conda packages. Neither are available on conda-forge so we will need to build them ourselves. I will work on this next sprint.

It turns out that ts-develop pinned the version of pyqt which prevented PySide2 from updating to a newer version. This has been fixed by removing the pyqt dependency from ts-develop and by moving all PySide2 dependencies from the base-sqre Dockerfile to ts-develop. Petr helped me locate the correct conda packages for PySide2 and PySide6. Now the installation works fine. I am building an docker.io/lsstts/develop-env:PYSIDE Docker image for Te-Wei and Petr to test.

I prepared the ts-dockerhub.lsst.org/develop-env:PYSIDE docker image containing both PySide2 and PySide6 and asked Petr Kubanek and Te-Wei Tsai to test it.

Please try out the develop-env docker image I created and mark this ticket as Reviewed when you're happy with it.

Looks good to me. I would test the docker image at DM-37454. It might happen in the next week. If there was the problem, we could reopen this ticket. Thanks!

Thanks Te-Wei. I'd prefer a new ticket in case of a problem but we can discuss that if any is found.

I created a docker.io image as well, since Te-Wei doesn't have a ts-dockerhub account. The image can be found on docker.io/wvreeven/develop-env.
