At present, ubutun version update iteration is too fast ~ The maintenance period of the regular version is relatively short, basically within one year, only the image10.04,12.04,14.04And later16.04It will last for 3-5 years.
Last year, the latest version 13.04 has been suspended for several months. It was not possible to install any updates before. Only when I want to install some software will I find that the source is invalid!
It took only half a day to find a solution. All versions that stop maintenance can use the old source.
Not easy to write, reproduced please indicate the source: http://blog.csdn.net/jscese/article/details/39010273
