我尝试卸载 postgresql，但无法卸载。请提供建议。
答案1
我认为您是 Ubuntu 新手。sudo apt-get update <argument>只会更新存储库，它会显示错误，因为您有错误（坏）链接。更新存储库后，您必须运行sudo apt-get upgrade以下载并安装更新。因此，要完全更新您的 Ubuntu 电脑，您必须输入：
sudo apt-get update
sudo apt-get upgrade
第一个命令的更好命令是：
sudo apt-get update -fmy
- 该论点
f是为了修复未解决的（损坏的）依赖关系。 - 即使档案无法定位，
m也要尝试搜索。 - 这个论点
y是对每个查询都假设为是。
答案2
这是我修复它的方法：
sudo rm /var/lib/postgresql/$$$YOUR VERSION$$$/main/postmaster.pid
sudo chown postgres:postgres /etc/postgresql/$$$YOUR VERSION$$$/main/environment
sudo chmod u+rw,g+rw /etc/postgresql/$$$YOUR VERSION$$$/main/environment
sudo pkill postgresql
sudo service stop postgresql
sudo apt-get -f install
确保用你的 posgresql 版本替换。我的是 9.3（只需将光标放在那里并点击Tab）。
