Hey @EarthlingDavey 👋🏼 the issue is Nginx 1.26.2 - wr can lock the versions to 1.26.1, as we did in the Intranet Dockerfile and the build will engage.

[EarthlingDavey]

Good morning, I'm not convinced the nginx version is the issue.

If we split the lines of the dockerfile up, the error occurs at line

RUN hg clone -r 1.26.2-1 https://hg.nginx.org/pkg-oss/

It's caused by a bug in hr, from what I've read it's because of a bug in one of it's dependencies.

I'll explore rolling back to 1.26.1, hopefully that will sort it 🤞 though theres a chance it might not be so straightforward.

[EarthlingDavey]

I've just run docker compose build nginx and it's building ok.

There must have been some dependency that was broken on Fri but has been fixed over the weekend.
