Hi,

Do you have any plans to package rustc 1.89 for Ubuntu (either as
rustc-1.89 or via an update to the current rustc versioned packages)?

We are currently affected by this bug and are waiting for the fix that
landed in Rust 1.89. It would be very helpful to know whether packaging
1.89 is planned for the current Ubuntu releases or only for future ones.

If it is planned, do you happen to have an approximate timeline for when
it might become available?

Thanks for your work maintaining the Rust packages!

Bug description:
  Hello!

  I actually tried rustc-1.85, 1.89, 1.84, 1.83, and all of them fail.
  Looks like only 1.82 version (cargo-1.82) works and < 1.82 including
  default 1.75.

  Checked both Ubuntu 22.04 and 24.04. Both are the same.

  The problem happens when git-ssh dependencies are used. Looks like
  this may be related to incompatibility of cargo and libgit versions.
