无法在 ubuntu 16.04 上安装 pgadmin3

Question

在我尝试后，sudo apt-get install pgadmin3我收到此消息：

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:
 pgadmin3 : Depends: libwxbase2.8-0 (>= 2.8.12.1) but it is not installable
            Depends: libwxgtk2.8-0 (>= 2.8.12.1) but it is not installable
            Recommends: pgagent but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

我该如何解决这个问题？

Answer 1

我遇到了同样的问题，经过足够长的时间，我意识到我的资源中有一个过时的 pgdg.list。删除并重新添加后，一切都很好。

sudo rm /etc/apt/sources.list.d/pgdg.*
echo "deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main" | sudo tee /etc/apt/sources.list.d/pgdg.list
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update -y
sudo apt-get install pgadmin3

Answer 2

尝试将以下存储库添加到系统中：

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 -

我有同样的问题，它对我有帮助。

Answer 3

我遇到了同样的问题，这里是如何修复它的：
1）当我尝试运行sudo apt-get install libwxbase2.8-0 libwxgtk2.8-0 apt-get 时告诉我，我有未使用的依赖项 - pgadmin3-data 和 pgagent，所以我最好删除它们
2）sudo apt autoremove- 删除它们
3）sudo apt-get install pgadmin3-告诉我它需要下载一些所需的依赖项（我刚刚删除的依赖项）。我说是的，这样安装就OK了
现在我可以使用pgadmin3了。
