Postgresql 无法在Ubuntu 19.04上安装Posgresql

键入

我如何解决这个错误并最终在我的ubuntu上安装Postgres

sudo apt-get update
sudo apt-get install postgresql postgresql-contrib

试着运行那个命令，让我知道你看到了什么。显然，postgres需要一些您尚未安装的软件包来解决未满足的依赖项错误，只需添加最新的PostgreSQL apt存储库即可

$ 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 -

然后只需启动更新命令

$ sudo apt-get update

之后，在您的情况下安装postgresql-11

$ sudo apt-get install postgresql-11

---

它不起作用<代码>以下软件包有未满足的依赖项：postgresql:Dependes:postgresql-11，但它不会被安装postgresql contrib:Dependes:postgresql-contrib-11 E:无法纠正问题，您持有的软件包已损坏。我无法在ubuntu 19上安装任何postgres 9/10/11-第一个答案有帮助。我只需要将apt存储库添加到Ubuntu19。
