Postgres卸载："server.key具有组或世界访问权限“错误

Question

我正在尝试卸载postgresql，但它确实是在抱怨。我怀疑有什么东西坏了。我在12.04，通过apt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/var/lib/postgresql/9.1/main/server.key，然后对其进行了建模：

chmod 700 server.key
chown postgres:postgres server.key

健全检查：

ls -l server.key

-rwx------ 1 postgres postgres 887 Jul 12 10:07 server.key

但是它仍然抱怨文件具有组访问权限。

如果有任何帮助来删除这一点，用install -f强制重新安装是没有帮助的。:(

通过清除这个包裹修复了

sudo apt-get purge postgresql-common
