[Bug]: Can't install rust; pkg upgrade tries to remove it if it's already installed (libllvm too new)

[Rhys-T]

Problem description

I was trying to run pkg upgrade, and discovered that apt wanted to remove rust for some reason. I eventually figured out that libllvm was trying to upgrade to version 17.x, and rust was still 1.72.1 and wouldn't work with that. (See also #17751, #18027.) Since pkg uses apt full-upgrade rather than apt upgrade, it's willing to uninstall any package that gets in the way of upgrading other packages.

If I move .../usr aside and relaunch to get a fresh prefix, I can't install rust at all because of the version mismatch.

For now, I've used apt-mark hold libllvm to make it ignore that upgrade (and the matching clang, etc. upgrades) and go ahead with everything else. I'll run apt-mark unhold libllvm once the new version of rust is available.

(I wasn't sure whether to file this as a 'bug report', or a 'package request' for the new version of rust. I went with 'bug report' because of the effect it was having on upgrading, but feel free to change it if that wasn't right.)

What steps will reproduce the bug?

With rust (and libllvm 16) already installed:

$ pkg upgrade

Without rust installed (e.g. in fresh prefix):

$ pkg install rust

What is the expected behavior?

No response

We are updating packages, it will be fixed soon.

Sounds good. Just wanted to check, and include the workaround I was using in case anyone else was having that problem.

As you found, the rust package needs to be updated, and probably will be in the next day.
