问题： apt-get install *** 一直出现 E: 无法定位软件包解决办法：vi /etc/apt/sources.list换apt软件源（例如清华大学镜像源）将第二行加 # 注释 后面加入并保存deb https://mirrors.tuna.tsinghua.edu.cn/deepin/ stable main contrib non-freedeb https://mirrors.tuna.tsinghua.edu.cn/deepin/ trusty main universe non-free我安装的系统是deepin所以为/deepin/，可以打开网页自己根据系统挑选文件夹stable main contrib non-free 这部分是release文件的文件夹更新sudo apt-get updatesudo apt-get upgrade转自：https://blog.csdn.net/qq_45555187/article/details/106532641?utm_medium=distribute.pc_relevant.none-task-blog-title-11&spm=1001.2101.3001.4242

已经通过apt-get install *ssl* 后执行configure操作 ./configure --prefix=/usr/local/nginx --with-http_ssl_module，依然提示如下错误。：./configure: error: SSL modules require the OpenSSL library.

求助：1.usb连接开发板和服务器，连接成功2.开发板通过网线连接上网，可以ping通百度，但无法apt-get update，更新源失败3.wget www.baidu.com 同样无法成功大佬 救命~

使用前提容器环境具有root权限北京一和北京四可以配置apt源动态安装linux 工具静态配置方式：/etc/apt/sources.list文件内容需要进行如下配置deb http://repo.myhuaweicloud.com/ubuntu/ xenial main multiverse restricted universedeb http://repo.myhuaweicloud.com/ubuntu/ xenial-backports main multiverse restricted universedeb http://repo.myhuaweicloud.com/ubuntu/ xenial-proposed main multiverse restricted universedeb http://repo.myhuaweicloud.com/ubuntu/ xenial-security main multiverse restricted universedeb http://repo.myhuaweicloud.com/ubuntu/ xenial-updates main multiverse restricted universedeb-src http://repo.myhuaweicloud.com/ubuntu/ xenial main multiverse restricted universedeb-src http://repo.myhuaweicloud.com/ubuntu/ xenial-backports main multiverse restricted universedeb-src http://repo.myhuaweicloud.com/ubuntu/ xenial-proposed main multiverse restricted universedeb-src http://repo.myhuaweicloud.com/ubuntu/ xenial-security main multiverse restricted universedeb-src http://repo.myhuaweicloud.com/ubuntu/ xenial-updates main multiverse restricted universe动态配置方式deb http://repo.myhuaweicloud.com/ubuntu/ xenial main multiverse restricted universedeb http://repo.myhuaweicloud.com/ubuntu/ xenial-backports main multiverse restricted universedeb http://repo.myhuaweicloud.com/ubuntu/ xenial-proposed main multiverse restricted universedeb http://repo.myhuaweicloud.com/ubuntu/ xenial-security main multiverse restricted universedeb http://repo.myhuaweicloud.com/ubuntu/ xenial-updates main multiverse restricted universedeb-src http://repo.myhuaweicloud.com/ubuntu/ xenial main multiverse restricted universedeb-src http://repo.myhuaweicloud.com/ubuntu/ xenial-backports main multiverse restricted universedeb-src http://repo.myhuaweicloud.com/ubuntu/ xenial-proposed main multiverse restricted universedeb-src http://repo.myhuaweicloud.com/ubuntu/ xenial-security main multiverse restricted universedeb-src http://repo.myhuaweicloud.com/ubuntu/ xenial-updates main multiverse restricted universe将以上内容放到sources.list中，上传到obs上，将文件放到启动目录中，这时代码会在启动时下载到训练环境中，在python代码中增加以下逻辑：os.system('sudo rm /etc/apt/sources.list; sudo mv /home/work/user-job-dir/<YOUR-CODE-DIR>/sources.list /etc/apt/sources.list; sudo apt-get update; sudo apt-get install <YOUR-REQUIRED-SOFTWARE>')

今天在使用云服务器安装东西的时候，更新软件包，突然发现失败了，出现了以下情况：苦苦寻找原因，网上各种答案，都没能成功解决问题，后来把出错的英语翻译了一下，大概的意思就是，获取包返回失败，后来想想是不是DNS的问题,然后重点来了我输入：cat /etc/resolv.confroot@whcckj:~# cat /etc/resolv.conf# This file is managed by man:systemd-resolved(8). Do not edit.## This is a dynamic resolv.conf file for connecting local clients to the# internal DNS stub resolver of systemd-resolved. This file lists all# configured search domains.## Run "systemd-resolve --status" to see details about the uplink DNS servers# currently in use.## Third party programs must not access this file directly, but only through the# symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way,# replace this symlink by a static file or a different symlink.## See man:systemd-resolved.service(8) for details about the supported modes of# operation for /etc/resolv.conf.nameserver 127.0.0.53search openstacklocal标蓝的地方就是问题所在，于是我们修改这个标蓝的地方vi /etc/resolv.conf改成 namesever 8.8.8.8 保存退出（先按下ESC,在输入：wq，回车搞定），然后使用sudo apt-get update
