apt的三种参数update upgrade dist-upgrade的区别
- update 更新源
update is used to resynchronize the packageindex files from their sources.
The indexes of available packages are fetchedfrom 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 newestversions 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 lessimportant ones if necessary.
