Hi Daniel,

Thanks for reporting this. I've confirmed the bug on both Noble and
Jammy. rustfmt should indeed depend on libstd-rust-1.75 (as it does in
more recent versions).

Bug description:
  This concerns rustfmt 1.75.0+dfsg0ubuntu1~bpo0-0ubuntu0.22.04 on
  Ubuntu jammy.

      $ /usr/bin/rustfmt --help
  /usr/bin/rustfmt: error while loading shared libraries: librustc_driver-234e49097c8e48f4.so: cannot open shared object file: No such file or directory

  That file is provided by the libstd-rust-1.75 package, at

      /usr/lib/x86_64-linux-gnu/librustc_driver-234e49097c8e48f4.so

  This is the current dependency field for rustfmt:

      Depends: libc6 (>= 2.34), libgcc-s1 (>= 4.2)

  Was the Rust runtime intended to be statically linked?
