我想将apache2 v2.2升级到v2.4，然后使用命令行按照on this site说明进行操作：
# apt-get install apache2 apache2.2-common apache2-mpm-prefork apache2-utils
Reading package lists... Done
Building dependency tree
Reading state information... Done
**apache2 is already the newest version.**
apache2-utils is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies.
apache2-mpm-prefork : Depends: apache2.2-bin (= 2.2.22-1ubuntu1.10) but it is not going to be installed
apache2.2-common : Depends: apache2.2-bin (= 2.2.22-1ubuntu1.10) but it is not going to be installed
**E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).**
它说已安装，然后我运行：
# service apache2 status
apache2: unrecognized service
然后我运行命令行：
#apt-get -f install
The following extra packages will be installed:
apache2-mpm-worker apache2.2-bin apache2.2-common
Suggested packages:
apache2-doc apache2-suexec apache2-suexec-custom
The following NEW packages will be installed
apache2-mpm-worker apache2.2-bin apache2.2-common
0 to upgrade, 3 to newly install, 0 to remove and 3 not to upgrade.
1 not fully installed or removed.
Need to get 0 B/1,572 kB of archives.
After this operation, 4,568 kB of additional disk space will be used.
Do you want to continue [Y/n]?
