在ubuntu 19.10上安装postgresql

Question

我正在尝试在ubuntu 19.10 (Eoan)上安装postgresql。我尝试过很多方法，但似乎连最新版本的postgresql (12)都不支持。有没有人知道它是否可以以某种方式安装？

这是我在尝试安装postgresql 11时收到的错误：

$ sudo apt-get install postgresql-11

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 postgresql-11 : Depends: postgresql-client-11
                 Depends: libicu55 (>= 55.1-1~) but it is not installable
                 Depends: libpq5 (>= 9.3~) but it is not going to be installed
                 Depends: libssl1.0.0 (>= 1.0.2~beta3) but it is not installable
                 Recommends: sysstat but it is not going to be installed
