Describe the bug, including details regarding any error messages, version, and platform.

The test-ubuntu-24.04-cpp-gcc-14 job has started failing to install clang-14 and llvm14, see:

As far as I can see nothing has changed here and the ppa repo is supposed to have gcc-14: https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/ppa

The error I get locally is slightly different that's why I was investigating gcc-14. When I run $ GCC_VERSION=14 UBUNTU=22.04 archery docker run -e SETUPTOOLS_SCM_PRETEND_VERSION="16.0.0.dev496" -e CC=gcc-14 -e CXX=g++-14 -e RapidJSON_SOURCE=BUNDLED ubuntu-cpp I get:

@raulcd You need UBUNTU=24.04 not 22.04

I cannot reproduce here. The image builds successfully. I used:

$ ARCHERY_USE_DOCKER_CLI=1 ARCHERY_DEBUG=1 GCC_VERSION=14 UBUNTU=24.04 archery docker run -e SETUPTOOLS_SCM_PRETEND_VERSION="16.0.0.dev496" -e CC=gcc-14 -e CXX=g++-14 -e RapidJSON_SOURCE=BUNDLED ubuntu-cpp bash

Edit: sorry, I was mistaken. This was because the corresponding steps were cached. If I disable caching (by adding --no-leaf-cache --force-build to the Archery command line), then I can reproduce the issue.

Ok, it seems that for some reason LLVM 14 has disappeared from the Ubuntu 24.04 packages. Later versions are available, I'm going to give it a try.

Hmm. It seems that llvm-14 doesn't exist only for amd64: https://packages.ubuntu.com/noble/llvm-14

Based on https://launchpad.net/ubuntu/+source/llvm-toolchain-14/+publishinghistory , the latest version is 1:14.0.6-19build4 but https://packages.ubuntu.com/noble/llvm-14 is ...build2.

[kou]

http://archive.ubuntu.com/ubuntu/pool/universe/l/llvm-toolchain-14/ has
llvm-14_14.0.6-19build2_i386.deb but it doesn't have
llvm-14_14.0.6-19build2_amd64.deb.

Both of llvm-14_14.0.6-19build4_{amd64,i386}.deb exist.
