満たされていない依存関係を修正できませんでした。

私のパイにSambaを設定しようとしていますが、依存関係が満たされていないため失敗します。これを出力する:

pi@octopi:~ $ sudo apt-get install samba samba-common-bin

You might want to run 'apt --fix-broken install' to correct these.

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

私は以下を試しました：

sudo apt --fix-broken install
sudo apt-get install -f
sudo apt-get update --fix-missing

これらは一般的にこれを出力する。出力：
