查看帮助信息`apt-get --help`

update - Retrieve new lists of packages
    upgrade - Perform an upgrade
    dist-upgrade - Distribution upgrade, see apt-get(8)

*  update 更新源

update is used to resynchronize the packageindex files from their sources. 
    The indexes of available packages are fetched from the location(s) 
    specified in /etc/apt/sources.list.

*  upgrade 升级软件包(有冲突则优先保留当前版本，不做升级)

upgrade is used to install the newest versions of all packages currently installed 
    on the system from the sources enumerated in /etc/apt/sources.list.

*  dist-upgrade 智能升级

dist-upgrade in addition to performing the function of upgrade, 
    also intelligently handles changing dependencies with new versions of packages; 
    apt-get has a"smart" conflict resolution system, 
    and it will attempt to upgrade the most important packages 
    at the expense of less important ones if necessary.
