debconf-i18n 依賴 debconf (= 1.5.58ubuntu2)；但是：系統上的 debconf 版本是 1.5.58ubuntu1

Question

當我嘗試在 Ubuntu 16.04 中安裝 git 時，

 sudo apt-get install git

debconf-i18n : Depends: debconf (= 1.5.58ubuntu2) but 1.5.58ubuntu1 is to be installed
 git : Depends: liberror-perl but it is not going to be installed
       Depends: git-man (> 1:2.7.4) but it is not going to be installed
       Depends: git-man (< 1:2.7.4-.) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

為了解決這個問題，

sudo apt-get install --reinstall debconf=1.5.58ubuntu2

但我收到以下錯誤。

/var/lib/dpkg/info/debconf.prerm: 15: /var/lib/dpkg/info/debconf.prerm: pyclean: not found
dpkg: warning: subprocess old pre-removal script returned error exit status 127
