升级误差

Question

当我进行apt-获取更新// apt-获取升级时，无论我做什么，我都收到了这个错误：

root@debian:~# apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 curl : Depends: libcurl3 (= 7.26.0-1+wheezy3) but 7.21.0-2.1+squeeze2 is installed
 multiarch-support : Depends: libc6 (>= 2.13-5) but 2.11.3-4 is installed
E: Unmet dependencies. Try using -f.
root@debian:~#

这不是我的服务器，所以我不知道里面安装了什么，我只知道我需要将php从5.2升级到5.3。它告诉我已经安装了Zend，但我也不知道是哪个版本。我试过的第一件事是，每次我遇到这个错误。cat /etc/一期: Debian GNU/Linux 6.0 \n L

这是我的/etc/apt/sources.list.列表：

root@debian:~# cat /etc/apt/sources.list

# deb cdrom:[Debian GNU/Linux 6.0.6 _Squeeze_ - Official i386 NETINST Binary-1 20120930-15:55]/ squeeze main

#deb cdrom:[Debian GNU/Linux 6.0.6 _Squeeze_ - Official i386 NETINST Binary-1 20120930-15:55]/ squeeze main

deb http://ftp.es.debian.org/debian/ squeeze main
deb-src http://ftp.es.debian.org/debian/ squeeze main

deb http://security.debian.org/ squeeze/updates main
deb-src http://security.debian.org/ squeeze/updates main

# squeeze-updates, previously known as 'volatile'
deb http://ftp.es.debian.org/debian/ squeeze-updates main

deb http://ftp2.de.debian.org/debian squeeze main non-free

root@debian:~#

这是我使用apt安装-f curl的输出：

root@debian:~# apt-get install -f curl
Reading package lists... Done

Reading state information... Done
curl is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 curl : Depends: libcurl3 (= 7.26.0-1+wheezy3) but 7.21.0-2.1+squeeze2 is to be installed
 multiarch-support : Depends: libc6 (>= 2.13-5) but 2.11.3-4 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Answer 1

原始错误也给出了解决方案：

You might want to run 'apt-get -f install' to correct these.

如果您以前没有见过这个命令，那么必须运行该命令。否则，你会得到：

Try 'apt-get -f install' with no packages (or specify a solution).

这通常能解决问题。

Answer 2

Michael已经提供了解决方案来解决依赖问题。为了进一步说明，apt-get upgrade将升级所有已安装的软件包。如果您想使用只升级一个包，请使用apt-get install package_name。对于PHP，可能是apt-get install php5。

此外，如果在更新包源时经常出现问题，您可以返回到发行版的“正式包列表”。Debian源列表生成器提供了一个交互式接口来为任何发行版生成源列表。
