我在 Dell Vostro 15 3000 系列笔记本电脑上安装了 Ubuntu 12.04。当我点击
sudo apt-get update
它工作正常，然后我点击
sudo apt-get upgrade
它告诉我：
然后当我按下Y它时出现如下错误：

现在我该怎么做才能解决这个问题并进行升级？
答案1
您可以通过运行来解决您的问题：
sudo nano /var/lib/dpkg/info/postgresql*.prerm
添加
exit 0
紧接着
#!/bin/sh
set -e
因此新文件将是这样的：
#!/bin/sh
set -e
exit 0
VERSION=9.1
. /usr/share/postgresql-common/maintscripts-functions
stop_version $VERSION
if [ "$1" = remove ]; then
remove_version $VERSION
fi
现在运行
sudo apt-get upgrade
这应该有效
