postgresql - 无法在 Ubuntu 19.04 上安装 Posgresql

问题描述

打字sudo apt-get install postgresql-11给我错误：

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
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

如何解决此错误并最终在我的 ubuntu 上安装 Postgres？

解决方案

要解决未满足的依赖项错误，只需添加最新的 PostgreSQL apt 存储库

$ sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ `lsb_release -cs`-pgdg main" >> /etc/apt/sources.list.d/pgdg.list'
$ wget -q https://www.postgresql.org/media/keys/ACCC4CF8.asc -O - | sudo apt-key add -

然后只需触发更新命令

$ sudo apt-get update

之后在你的情况下安装 postgresql-11

$ sudo apt-get install postgresql-11
