@jhollowe , @ThatKalle any ideas?

[Paplewski]

there is no signature file to download for latest python 3.14.

just change it manually to 3.13 for now:

diff --git a/.devcontainer/devcontainer.json b/.devcontainer/devcontainer.json

See: devcontainers/features#1501 and https://docs.python.org/3.14/whatsnew/3.14.html#whatsnew314-no-more-pgp

The fix until the upstream is patched (Looks like there is a PR already: devcontainers/features#1503) is to "downgrade" to a non-latest version indeed.

• Or handle the installation of Python 3.14 from within the devcontainer Dockerfile.
• Or swap to let the devcontainer.json use a differet "feature" to install Python, for example the mise based one, I've not tried that one myself, but I've heard good things about mise.

Is 3.14 needed in the devcontainer? The builder Dockerfiles do use it, ideally they should probably align.

I can confirm that stepping back to "version": "3.13.8" does work. (Atleast to bring the devcontainer up).
