• apt-get update报错解决方法

    前言

           经过反复折腾，总结一下，最后最有效的还是是从别的ubuntu中复制一份source.list过来，其他的方法都会有各种各样的后遗症。

       出错解析    

             这个错误呢,我的起因是因为以前改过/etc/apt/source.list文件，我觉得这种问题最快的解决方法就是，删掉它，然后重新弄一个管用的/etc/apt/source.list过来.

            大家看到/etc目录，要有那种第一反应就是，啊，这个是linux启动配置目录，然后再看到apt，就会联想到，啊，原来是apt软件在etc目录的配置目录，就是apt软件的配置文件，如果能有这个觉悟，其他的就大胆联想，大胆尝试吧。

    二 解决方案

    1.进入/etc/apt/目录，将source.list文件重命名为source.list.backup

    2，新建source.list文件

    3.将下面的内容放到source.list文件中

    1. # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
    2. # newer versions of the distribution.
    3. deb http://archive.ubuntu.com/ubuntu/ focal main restricted
    4. # deb-src http://archive.ubuntu.com/ubuntu/ focal main restricted
    5.  
    6. ## Major bug fix updates produced after the final release of the

    49. # deb-src http://security.ubuntu.com/ubuntu/ focal-security multiverse
    50.

    然后就可以$ sudo apt-get update

    1. kmao@lkmao-ubuntu:/etc/apt$ sudo apt-get update
    2. 获取:1 http://archive.ubuntu.com/ubuntu focal InRelease [265 kB]
    3. 获取:2 http://security.ubuntu.com/ubuntu focal-security InRelease [114 kB]
    4. 获取:3 http://archive.ubuntu.com/ubuntu focal-updates InRelease [114 kB]
    5. 获取:4 http://archive.ubuntu.com/ubuntu focal-backports InRelease [108 kB]
    6. 获取:5 http://security.ubuntu.com/ubuntu focal-security/main amd64 Packages [1,705 kB]
    7. /*略*/
    8. 获取:108 http://archive.ubuntu.com/ubuntu focal-backports/universe DEP-11 64x64@2 Icons [29 B]
    9. 获取:109 http://archive.ubuntu.com/ubuntu focal-backports/universe amd64 c-n-f Metadata [860 B]
    10. 获取:110 http://archive.ubuntu.com/ubuntu focal-backports/multiverse amd64 c-n-f Metadata [116 B]
    11. 已下载 51.8 MB，耗时 20秒 (2,623 kB/s)                                         
    12. 正在读取软件包列表... 完成
    13.  
    14. lkmao@lkmao-ubuntu:/etc/apt$
    15.

    三 如果直接删除source.list会怎么样？

    这个简单，直接重命名就可以，现象也很简单，如下所示:

    1. lkmao@lkmao-ubuntu:/etc/apt$ sudo apt-get update
    2. 正在读取软件包列表... 完成

    试完了，记得把名字改回来。

    四 如果还不能解决问题，怎么办？

            新安装一个虚拟机，将虚拟机中的/etc/apt目录中的文件打包，然后复制到出问题的ubuntu虚拟机中。

    验证下:(⊙o⊙)，我都安装新的系统了，为啥还要解决这个问题啊？用新的。

    总结

            加油。
