我正在尝试卸载 postgresql，但它确实在抱怨。我怀疑有什么东西坏了。我使用的是 12.04，通过 apt-get 安装。
sudo apt-get remove postgresql
返回：

现在我尝试修复 server.key 文件；我将蛇油文件复制到然后/var/lib/postgresql/9.1/main/server.key对其进行了修改：
chmod 700 server.key
chown postgres:postgres server.key
完整性检查：
ls -l server.key
-rwx------ 1 postgres postgres 887 Jul 12 10:07 server.key
但它仍然抱怨该文件具有群组访问权限。
非常感激任何帮助删除此问题的信息，强制重新安装install -f没有帮助。:(

通过清除此包修复
