You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
php: Obsoletes: php-imap but 4.3.4-11 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

不满足依赖性的问题，可以使用 'apt-get -f install'

[root@locolhost root]#地衣歌还是不幸

信息很明白，要你apt-get -f install或apt-get -f dist-upgrade用f选项解决依赖性问题。
