Can't install LLVM 19 on debian using llvm.sh

[ChrisGreenaway]

Building the Dockerfile:

FROM debian:bullseye

RUN apt update && apt --yes upgrade
RUN apt install --yes curl lsb-release wget software-properties-common gnupg
RUN curl -sL https://apt.llvm.org/llvm.sh | bash -s -- 19 all

fails with the error:

7.558 The following packages have unmet dependencies:

Also fails on debian:bookworm, although with a slightly different error.

It looks like Noble's packages haven't been updated in a while:

libclang-cpp19 is already the newest version (1:19.1.0~++20240910033111+327ca6c02f0d-1~exp1~20240910153233.33).

Baffling...

Maybe something is wrong with these directives in llvm-19-dev?

Looks like the fix is already committed https://salsa.debian.org/pkg-llvm-team/llvm-toolchain/-/commit/3ab346721f6f7592a5139969889c3107ca107ca7
Maybe it just takes that long to rebuild packages

[OmriSteiner]

Sound similar to #101201.
At this point I'm considering building LLVM from source

[vient]

@sylvestre can you please trigger a (Focal) packages rebuild? I see that fixes were already committed yesterday but builds do not start automatically - source trigger is set up only on LLVM repo itself, not on your packaging repo.

[sylvestre]

sure, builds started

[ChrisGreenaway]

This seems to work fine now. Thanks

There are similar error in Debian sid when I upgrade to libllvm19:i386 1:19.1.0-3.

$ sudo apt update && sudo apt upgrade -y
You might want to run 'apt --fix-broken install' to correct these.
Unsatisfied dependencies:
 mesa-libgallium:i386 : Depends: libllvm19:i386 (>= 1:19.1.0) but it is not installed
 mesa-vulkan-drivers:i386 : Depends: libllvm19:i386 (>= 1:19.1.0) but it is not installed
Error: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

And then, I run apt --fix-broken install:

Error: Installation has failed.

When I run ls -alh /usr/lib/llvm-19/lib:

libLLVM.so.19.1 -> ../../x86_64-linux-gnu/libLLVM.so.19.1

Looks like x86_64 and i386 have same symbolic link, and I don't know it's Debian sid bug or llvm bug.

@haxung this is unrelated and it will be fixed tomorrow
