Title:
  rustc is not getting new versions in Ubuntu 24.04

Status in rustc package in Ubuntu:
  In Progress

Bug description:
  Both Ubuntu 22.04 and 24.04 have rustc 1.75, with additional versions
  up to 1.80 in packages like rustc-1.77. However Rust 1.81 is not
  available from the official repository of any LTS version (only
  oracular and newer).

  Rust 1.80 was released in July 2024, not long after 24.04 itself was
  released. I would have naively expected additional packages in 24.04
  to go on until July 2026, but that doesn't seem to be the case. QEMU
  is planning to introduce Rust (with a target of supporting Rust 1.83
  and newer); it would be a regression if it is not possible to build
  even on the latest Ubuntu LTS release.

  Is it planned to update the base rustc (plus rust libstd etc.) package
  in 24.04 or alternatively to upload alternative Rust packages for
  versions newer than 1.80? This situation where one LTS release got new
  versions of the language multiple times over two years, and the other
  basically never had any update, is confusing.

  (I have already asked at askubuntu.com but got no answer).
