Postgres-xc 无法卸载(停止协调器失败)

Postgres-xc 无法卸载(停止协调器失败)

我正在进行一些 rails 开发,不小心安装了 postres-xc 而不是正常的 postgres 包。我立即删除了 postgres-xc,但 apt-get 不会卸载它。我也尝试安装常规的 postgres,但同样失败了。

sudo apt-get remove postgres-xc 输出:

Use 'apt-get autoremove' to remove them.

我发现它至少是部分卸载,因为如果不使用 apt-get -f install 来修复它,我就无法安装任何其他东西。

似乎也是一个已知问题

有什么办法可以让我手动将其从安装中删除吗?

修复。解决方案是 dpkg --purge postgres-xc

答案1

对我有用的解决方案是:

  1. 修改postgres-xc.prerm:

    sudo vim /var/lib/dpkg/info/postgres-xc.prerm

    在第一行后添加“exit 0”(#/bin/sh -e)

  2. 然后正常删除:

    sudo apt-get 删除 postgres-xc
