These messages with "only only (n)/(n+1) of needed bytes read" seem to
be characteristic. As well as being a FTBFS, this is also an autopkgtest
regression when upgrading curl, which is one of several factors preventing
curl from migrating; that, in turn, blocks elfutils, which blocks GLib,
which will likely be blocking a significant chunk of the 64-bit time_t
transition.
This could either be a regression in curl, or a pre-existing bug in
ruby-curb that was exposed by a behaviour change in curl (for example
maybe curl started applying stricter checks). I don't know curl well
enough to say which, but perhaps the curl maintainers can help? This
upstream commit introduced the new error message and seems relevant:
https://github.com/curl/curl/commit/9369c30cd87c041cf983bcdfabd1570980abbaf6
Here is a convenient reproducer in an unprivileged container:
$ podman run -v $(pwd):$(pwd):rw -w $(pwd) -it debian:trixie-slim
# sed -i -e 's/Types: deb/& deb-src/' /etc/apt/sources.list.d/debian.sources
# apt update
# apt upgrade
# apt install --no-install-recommends build-essential
# apt source ruby-curb
# cd ruby-curb-*
# apt --no-install-recommends build-dep .
# dpkg-buildpackage -us -uc -B
... succeeds ...
# sed -i -e 's/Suites: trixie /Suites: sid /'
# apt --no-install-recommends install curl
...
The following additional packages will be installed:
libcurl3t64-gnutls libcurl4-gnutls-dev libcurl4t64
Suggested packages:
libcurl4-doc libgnutls28-dev libidn-dev libkrb5-dev libldap2-dev librtmp-dev
libssh2-1-dev pkgconf zlib1g-dev
The following packages will be REMOVED:
libcurl3-gnutls
The following NEW packages will be installed:
curl libcurl3t64-gnutls libcurl4t64
The following packages will be upgraded:
libcurl4-gnutls-dev
...
# dpkg-buildpackage -us -uc -B
... fails as seen in the buildd log ...
Thanks,
