CI failure unrelated :v

[alexcrichton]

As-is the case with #577, can you add CI here for the version that you're interested in?

[nabijaczleweli]

Added rustc 1.75 (Ubuntu LTS 24.04). 1.63 (Debian Bookworm) would also be nice but that pre-dates fetchable registries, so that's an excessive burden I think.

The x86_64-musl failure seems unrelated (curl openssl.tar.gz | tar -xz fails to decompress as gzip?).

[alexcrichton]

Thanks! I think the CI failure is the need to update this line too?

[nabijaczleweli]

Survey says: no (but I did update that too, thanks).

I wanna say that if you trigger a build on trunk it will happen too? This smells like a mirror issue (if I repeat the failing curl locally I get a valid gzip stream).

[nabijaczleweli]

Actually no, I wgetted it 💀 curl https://www.openssl.org/source/old/1.0.2/openssl-1.0.2g.tar.gz | tar tzf - does fail.

perl curl -v this just wants -L:

yup, that fixed it. and the 1.75 job works too
