执行 sudo apt-get install 或类似命令时，我收到此消息：
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
postgresql-client-9.1 : Breaks: postgresql-9.1 (< 9.1.11-1.pgdg12.4+1) but 9.1.10-1.pgdg12.4+1 is to be installed
postgresql-contrib-9.1 : Depends: postgresql-9.1 (= 9.1.11-1.pgdg12.4+1) but 9.1.10-1.pgdg12.4+1 is to be installed
synaptic : Depends: libvte9 (>= 1:0.24.0) but it is not going to be installed
Recommends: rarian-compat but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
Ubuntu 软件中心和更新管理器也不起作用 - 软件中心一直尝试修复，但从未成功，apt-get -f install 没有帮助（修复因这些软件包而取消）。所有错误消息都与这些软件包有关。
我能做些什么来让它工作吗？

答案1
尝试通过运行以下命令强制删除软件包，
sudo dpkg --purge --force-all --force-remove-reinstreq postgresql-9.1 postgresql-9.1-postgis-2.0 postgresql-9.1-pgrouting postgresql-contrib-9.1
然后运行，
sudo apt-get -f install
在这种情况下，任何其他方法都dpkg --purge --force-all --force-remove-reinstreq不起作用。
