概述我是postgre和Ubuntu的新手.我正在使用Ubuntu 14.04 LTS Trusty运行VM.我正在尝试安装PostgreSql9.4数据库和PostGIS 2.1.这是我在Ubuntu机器上运行的命令： sudo apt-get install wget ca-certificates sudo sh -c 'echo "deb http://apt.postgresql.org/ 我是postgre和Ubuntu的新手.我正在使用Ubuntu 14.04 LTS Trusty运行VM.我正在尝试安装Postgresql9.4数据库和PostGIS 2.1.这是我在Ubuntu机器上运行的命令： @H_502_1@sudo apt-get install wget ca-certificates sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt trusty-pgdg main" >> /etc/apt/sources.List'wget --quIEt -O - http://apt.postgresql.org/pub/repos/apt/ACCC4CF8.asc | sudo apt-key add -sudo apt-get updatesudo apt-get upgradesudo apt-get install postgresql-9.4-postgis-2.1 pgadmin3 postgresql-contrib

但是我收到以下错误.

@H_502_1@The following packages have unmet dependencIEs: pgadmin3 : Depends: libwxbase3.0-0 (>= 3.0.0) but it is not installable Depends: libwxgtk3.0-0 (>= 3.0.0) but it is not installable Recommends: pgagent but it is not going to be installed postgresql-9.4-postgis-2.1 : Depends: libgdal1h (>= 1.9.0) but it is not installable Depends: libgeos-c1 (>= 3.4.2) but it is not installable Depends: liblwgeom-2.1.5 (>= 2.1.2) but it is not going to be installed Depends: libproj0 (>= 4.8.0-1) but it is not installableE: Unable to correct problems,you have held broken packages.

我搜索了几个地方,看到了很多回复,但没有一个对我有用.我也试过Postgresql9.3并且也没能成功.谢谢你的帮助.谢谢

您可能在postgresql的存储库中有更高版本的候选版本,然后在您的官方发行版中(因此未完成的依赖项).一种可能的解决方案是通过检查它们是否可用作候选(apt-cache策略)并选择要安装的特定版本(也用于依赖项)来从发行版通道安装相同的软件包.

在我的系统上,它看起来如下：

@H_502_1@The following packages have unmet dependencIEs: pgadmin3 : Depends: libwxbase3.0-0 (>= 3.0.2) but it is not installable Depends: libwxgtk3.0-0 (>= 3.0.2) but it is not installable Recommends: pgagent but it is not going to be installedapt-cache policy pgadmin3pgadmin3: Installed: (none) CandIDate: 1.20.0-1.pgdg70+1 Version table: 1.20.0-1.pgdg70+1 0 500 http://apt.postgresql.org/pub/repos/apt/ wheezy-pgdg/main amd64 Packages 1.14.2-2 0 500 http://ftp5.gwdg.de/pub/linux/debian/debian/ wheezy/main amd64 Packages

然后,您希望安装较低版本：

@H_502_1@$sudo apt-get install pgadmin3=1.14.2-2 pgadmin3-data=1.14.2-2 总结
