Yesterday in the devs hangout we discussed about making a dockerbuild environment for testing 3D Slicer in newer Ubuntu distributions. I’ve looked at the existing `ubuntu-2004-gcc9/Dockerfile` and have a few questions:

1. The existing Ubuntu environments in the current [dockbuild](https://github.com/dockbuild/dockbuild/tree/b35d6d70e2b785d8dd5985422ddfd1fda8800909) all match `xx.04` releases. Did I understand correctly that we want to prepare an `ubuntu-2010-gcc10` environment?

2. These environments come with a thin layer of core packages provided by the package-manager (e.g., `libssl-dev` and `curl`) and scripts to build/install some other packages (e.g., `install-cmake-binary.sh` and `build-and-install-git.sh`). Why do some packages rely on the package-manager while others don’t? Should the version of the scripted packages (e…g, `ARG CMAKE_VERSION=...` correspond to that of the packages in the package-manager?

3. There are some Slicer dependencies that are not considered in `dockbuild` (e.g., Qt). What to do with these?

Thank you.

Hey 👋

20.04 is an LST release and 20.10 will reach end of life in less than 6 months (July 2021 as said [here](https://wiki.ubuntu.com/Releases))

For 3:

Once we have the dockbuild image set up, we will create an image for Slicer (see [SlicerBuildEnvironment](https://github.com/Slicer/SlicerBuildEnvironment) ) that takes care of Qt. The Qt stuff can be non-trivial, so if when you get to that point you find you are having issues, I can help out with that.

This scripts are copied from dockcross using [this script](https://github.com/dockbuild/dockbuild/blob/master/imagefiles/UpdateFromUpstream.sh).

There are useful to (for example) ensure we have a specific version of CMake available in all images.

If someone has bandwidth, it would be great to work on these issues as well:
