Debian Squeeze无法安装php-pear

我使用Debian 6.0.6

sudo apt-get install php-pear

结果是：

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:
 initscripts : Breaks: console-setup (< 1.74) but 1.68+squeeze2 is to be installed
               Breaks: initramfs-tools (< 0.104) but 0.98.8 is to be installed
               Breaks: nfs-common (< 1:1.2.5-3) but 1:1.2.2-4squeeze2 is to be installed

 klibc-utils : Breaks: initramfs-tools (< 0.103) but 0.98.8 is to be installed
E: Broken packages

我该如何解决？

您是在运行混合分发（稳定/测试/等）还是在使用辅助存储库？

cat /etc/debian_version

在这种情况下，您应该降级所有非主流软件包的版本，然后重试。

我敢肯定你做到了，但万一：

apt-get update 
apt-get upgrade
apt-get install php-pear 

尝试以此顺序执行命令。
