我用命令sudo apt-get install apache2并得到下面的错误：
有什么build议么？
# sudo apt-get install apache2 The following NEW packages will be installed: apache2 apache2-bin apache2-data libapr1 libaprutil1 libaprutil1-dbd-sqlite3 libaprutil1-ldap ssl-cert 0 upgraded, 8 newly installed, 0 to remove and 0 not upgraded.

阅读错误消息结尾处的build议。 您的源代码列表已过时。
在这里快速检查ubuntu包的网站，发现trusty-updates中apache2的当前版本号是2.4.7-1ubuntu4。 9
运行sudo apt-get update; sudo apt-get -uf upgrade sudo apt-get update; sudo apt-get -uf upgrade然后再次尝试命令。
