Debian Sidでlibc6をアップグレード中にエラーが発生しました。

Debian Sid をアップグレードしようとするとエラーが発生します。

Preparing to unpack .../libc6_2.30-3_amd64.deb ...
De-configuring libc6:i386 (2.30-2) ...

A copy of the C library was found in an unexpected directory:
  '/usr/lib/x86_64-linux-gnu/ld-2.30.so'
It is not safe to upgrade the C library in this situation;
please remove that copy of the C library or get it out of
'/usr/lib/x86_64-linux-gnu' and try again.

apt --fix-broken install は役に立ちません。ただこのエラーを返すだけです。もう一度アップグレードしようとした後、これは私に

The following packages have unmet dependencies:
 libc6-dev : Depends: libc6 (= 2.30-3) but 2.30-2 is installed
 libc6-i386 : Depends: libc6 (= 2.30-3) but 2.30-2 is installed

この問題を解決するにはどうすればよいですか？
