[Ubuntu]为什么有时在网上搜索安装某个包时会有推荐ppa?

Question

根据搜索结果ppa是一个类似社区驱动的仓库(原谅我描述不准确)

Always remember that PPAs are provided by the community, you should be aware of the possible risks before just adding a PPA.

我比较不理解的地方是: (有时候使用ppa作为仓库的理由是啥?)
其实Ubuntu的仓库里面的包已经很多很丰富很新了,为什么还要举出ppa(某些教程,尤其对于我来说ppa实在是太慢了)
仅仅是更新更丰富更多?

Answer 1

Give a few examples.

The status of the following software in the official source is:

golang1.5 (not available in the new version, seems to be only 1.2 or 1.3)

kubernetes(no)

sublime (commercial software, no)

chrome (no, only chromium)

jdk (commercial software, no, only openjdk. Using https://launchpad.net/~webupd8team/+archive/ubuntu/java cannot be more convenient)

Other commercial software testing software, not to mention software in development.

In addition, another benefit of PPA source is that it is convenient for package manager management and is deeply compatible with apt-get.
