この問題は、sudo apt-get updateの実行を忘れたようです。 odbcinst1debian2をインストールする前に 。 フォーカル このパッケージはmultiarch-supportに依存しません 。
ちなみにmultiarch-support 手動でインストールできます：
cd ~/Downloads
wget http://archive.ubuntu.com/ubuntu/pool/main/g/glibc/multiarch-support_2.27-3ubuntu1.4_amd64.deb
sudo apt-get install ./multiarch-support_2.27-3ubuntu1.4_amd64.deb
