Just hit this bug in my plucky, upgraded from noble.

`apt install --reinstall rustc` did not solve the issue, but `rm
/usr/share/rustc && apt install --reinstall rustc` did.

** Changed in: rust-defaults (Ubuntu)

Title:
  Missing files after upgrade from noble to oracular

Status in rust-defaults package in Ubuntu:
  Confirmed

Bug description:
  Starting from oracular, we transition from the non-versioned rustc to
  rustc-X.Y + rust-defaults. rust-defaults includes symlinks with non-
  versioned file paths to the versioned ones.

  This works correctly for oracular or plucky fresh installs. However,
  if you install rustc in noble and then upgrade the system to oracular,
  links to directories will be missing (e.g, /usr/share/rustc will be
  empty). This is most likely due to the lack of a breaks/replaces or a
  conflicts relation in the packages in rust-defaults.

  This can be reproduced by installing noble's rustc an then upgrading
  it to oracular's rust-defaults.
