通过简单的终端方式添加和删除更新通道

我知道Ubuntu中有一个GUI Software & Updates来启用更新通道

如以下屏幕截图所示：

我正在寻找一种使用以下命令从终端内部执行此操作的简便方法

sudo apt-add-update enable updates
sudo apt-add-update enable proposed
sudo apt-add-update enable backports
sudo apt-add-update enable security

sudo apt-add-update disable updates
sudo apt-add-update disable proposed
sudo apt-add-update disable backports
sudo apt-add-update disable security

还有一件事

sudo apt-add-update enable default

sudo apt-add-update disable default

一些例子，以更好地理解

一个空的 sources.list
- cat /etc/apt/sources.list
```
<empty>
```
- sudo apt-add-update enable security
```
<empty>
```

一个启用的存储库（main）

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily main

sudo apt-add-update enable security

deb http://archive.ubuntu.com/ubuntu wily main
deb http://archive.ubuntu.com/ubuntu wily-security main

一行或两行中的两个或多个启用的存储库

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily main universe

要么

deb http://archive.ubuntu.com/ubuntu wily main
deb http://archive.ubuntu.com/ubuntu wily universe

sudo apt-add-update enable security

deb http://archive.ubuntu.com/ubuntu wily main universe
deb http://archive.ubuntu.com/ubuntu wily-security main universe

要么

deb http://archive.ubuntu.com/ubuntu wily main
deb http://archive.ubuntu.com/ubuntu wily-security main
deb http://archive.ubuntu.com/ubuntu wily universe
deb http://archive.ubuntu.com/ubuntu wily-security universe

带deb-src条目

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily main universe
deb-src http://archive.ubuntu.com/ubuntu wily main universe

sudo apt-add-update enable security

deb http://archive.ubuntu.com/ubuntu wily main universe
deb-src http://archive.ubuntu.com/ubuntu wily main universe
deb http://archive.ubuntu.com/ubuntu wily-security main universe
deb-src http://archive.ubuntu.com/ubuntu wily-security main universe

使用无效的deb-src条目

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily main universe
# deb-src http://archive.ubuntu.com/ubuntu wily main universe

sudo apt-add-update enable security

deb http://archive.ubuntu.com/ubuntu wily main universe
# deb-src http://archive.ubuntu.com/ubuntu wily main universe
deb http://archive.ubuntu.com/ubuntu wily-security main universe

该default事

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily-security universe

sudo apt-add-update enable default

deb http://archive.ubuntu.com/ubuntu wily universe
deb http://archive.ubuntu.com/ubuntu wily-security universe

只有一个条目和disable动作
- cat /etc/apt/sources.list
```
deb http://archive.ubuntu.com/ubuntu wily-security universe
```
- sudo apt-add-update disable security
```
<empty>
```

对于不同或相同存储库的不同或相同服务器，请尊重每个服务器

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily universe
deb http://us.archive.ubuntu.com/ubuntu wily main

sudo apt-add-update enable security

deb http://archive.ubuntu.com/ubuntu wily universe
deb http://us.archive.ubuntu.com/ubuntu wily main
deb http://archive.ubuntu.com/ubuntu wily-security universe
deb http://us.archive.ubuntu.com/ubuntu wily-security main

针对不同存储库的不同Ubuntu版本，请尊重每个版本

cat /etc/apt/sources.list

deb http://archive.ubuntu.com/ubuntu wily main universe
deb http://archive.ubuntu.com/ubuntu trusty main

sudo apt-add-update enable security

deb http://archive.ubuntu.com/ubuntu wily main universe
deb http://archive.ubuntu.com/ubuntu trusty main
deb http://archive.ubuntu.com/ubuntu wily-security main universe
deb http://archive.ubuntu.com/ubuntu trusty-security main

PPA或？中的其他软件包来源（非规范）sources.list？

忽视！
不要更改协议，例如https，http，tor，...

这完全符合要求。

如有必要，我会不时进行更新。

最新版本可在此GitHub存储库中找到；

要从GitHub存储库安装：

安装git：sudo apt-get install git
克隆存储库： git clone https://github.com/kos0/addRemoveDistribution.git

2015年11月27日更新：

脚本的第二版仍然令我不满意源代码的膨胀以及我不得不使用几种不同的工具这一事实。因此，我尝试仅在AWK中重写脚本。

新脚本使用纯AWK，并且更好地满足了要求。本质上，它/etc/apt/sources.list每次运行时都会重写。

运行脚本后，需要进行更新，因此sudo apt-get update，在脚本成功退出后运行。

该文件必须具有启用的可执行权限，chmod +x add-update.awk并且必须保存在该$PATH变量包含的任何目录中。特别建议将脚本保存到$HOME/bin文件夹（该文件夹也必须附加到$PATH变量中）。

/etc/apt/sources.list不需要备份原始文件，但强烈建议您备份。要备份文件

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

用法：

sudo ./add-update.awk -v ACTION=[enable|disable|help] -v SOURCE=[updates|backports|security|proposed]

我分析了用编写的Ubuntu Software Center的来源python。

            sourceentry = aptsources.sourceslist.SourceEntry(line)
            sourcelist.list.append(sourceentry)

    sourcelist.save()

将此代码保存为文件名/usr/local/bin/apt-add-update。然后按以下方式运行。

$ sudo apt-add-update <enable|disable> <default|updates|security|proposed|backports>

我更新了它以提供多发行版支持，例如trusty和wily。

用法：

## testing

apt-add-update  enable|disable  default|security|updates|proposed|backports  [file]


## real

sudo  apt-add-update  enable|disable  default|security|updates|proposed|backports

这里要点：

我解析该文件是因为我自己正在寻找其他选项。

检查是否有任何镜像，包括官方（旧版本，端口）或从python-apt软件包加载的社区提供的其他镜像（它包含具有所有镜像的文件）。
```
/usr/share/python-apt/templates/Ubuntu.mirrors
```
始终将官方URI保留在文件中。因此，即使禁用了所有功能，它也会为持久性设置保留一条注释行。它使用字母排序类型，url，dist，comp将行减至最少。
如果它获得输入文件作为第三个参数或没有写权限，则打印到标准输出 /etc/apt/sources.list
不支持[ options ]喜欢[ arch=amd64 ]。
删除disable default了我要求用户指定要禁用的内容。
我不喜欢最后一个选择（9），因为我是故意混用回购协议。因此，它们应被视为第三方存储库。

您可以使用来以非常简单的方式进行操作add-apt-repository。

例如，您可以添加proposed通过

sudo add-apt-repository "http://archive.ubuntu.com/ubuntu/ $(lsb_release -sc)-proposed restricted universe multiverse main"

它将添加deb和deb-src行/etc/apt/sources.list。但是源代码行将被注释。

如果add-apt-repository使用-s参数运行，它将不会被注释掉deb-src。

您可以security通过以下方式启用

sudo add-apt-repository "http://security.ubuntu.com/ubuntu/ $(lsb_release -sc)-security restricted universe multiverse main"

是的，我可以这样做。但是我需要存储库和服务器，而不仅仅是a add security或add proposed。

如问题中所述：“我正在寻找一种使用以下命令从终端内部执行此操作的简便方法……也许类似于：sudo apt-add-update security”

— AB

这个命令有什么问题？那很长吗？您可以通过进行更新sudo apt-get update。缩短命令非常容易。

是的sudo add-apt-repository "http://archive.ubuntu.com/ubuntu/ wily-proposed restricted universe multiverse main"，支持其他民族的时间太长了。我必须检索以前存在的存储库和使用的服务器。
