Question

键入sudo apt-get install postgresql-11会给我错误：

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
                 Recommends: sysstat but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

如何解决此错误并最终在Ubuntu上安装Postgres？

Answer 1

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 -

然后只执行更新命令

$ sudo apt-get update

在这种情况下，请安装postgresql-11

$ sudo apt-get install postgresql-11

Answer 2

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

尝试运行该命令，然后告诉我您所看到的内容。显然postgres需要一些尚未安装的软件包

无法在Ubuntu 19.04上安装Posgresql
