** Do you have the right repo manifest?
So I tried to install the JDK correctly by the following steps:
所以我尝试通过以下步骤正确安装JDK：
Step 1
步骤1
Uninstall everything JAVA related by following these steps.
Step 2
第2步
Install correct JAVA by following these steps. I used the default installer option and version 6, not 7 or 8
按照以下步骤安装正确的 JAVA 。我使用了默认安装程序选项和版本 6，而不是 7 或 8
Step 3
第 3 步
Here I am simply following this answer.
在这里，我只是按照这个答案。
sudo gedit .bashrc
Edit the file at the bottom by adding those lines
通过添加这些行来编辑底部的文件
JAVA_HOME=/usr/lib/jvm/java-6-oracle
export JAVA_HOME
# replacing /path/to/androidsdk/ with correct path of course..
export PATH=${PATH}:/path/to/androidsdk/android-sdk-linux/platform-tools
PATH=$PATH:$JAVA_HOME
# Variable ANDROID_JAVA_HOME
ANDROID_JAVA_HOME=/usr/lib/jvm/java-6-oracle
export ANDROID_JAVA_HOME
PATH=$PATH:$ANDROID_JAVA_HOME
Step 4
步骤4
Test what I've done so far:
测试我到目前为止所做的：
...:~$ echo $JAVA_HOME
/usr/lib/jvm/java-6-oracle
...:~$ java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) Server VM (build 20.45-b01, mixed mode)
...:~$ which java
/usr/bin/java
...:~$ echo $ANDROID_JAVA_HOME
/usr/lib/jvm/java-6-oracle
...:~$ echo $PATH
/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/lib/jvm/java-6-oracle/bin:/usr/lib/jvm/java-6-oracle/db/bin:/usr/lib/jvm/java-6-oracle/jre/bin:/path/to/androidsdk/android-sdk-linux/platform-tools:/usr/lib/jvm/java-6-oracle
Step 5
第 5 步
Go in terminal to the Android source folder and enter
在终端中进入 Android 源文件夹并输入
source build/envsetup.sh
Result:
结果：
including device/asus/grouper/vendorsetup.sh
including device/asus/tilapia/vendorsetup.sh

What did I do wrong? What is missing? What about the "Permission denied"?
我做错了什么？缺什么？“权限被拒绝”怎么办？

I found the solution:
我找到了解决方案：
For some reason I did not have the respective rights as the "Permission denied" would suggest. Setting the permissions for the Android source folder via chmod did the trick
I mistakenly downloaded the latest branch. However I only have a 32 bit system. For 32 bit you can only use Android source that is smaller than Android 2.3 and for those versions you also have to use JDK 5 http://source.android.com/source/building.html
出于某种原因，我没有“权限被拒绝”所暗示的相应权利。通过 chmod 设置 Android 源文件夹的权限就成功了
我错误地下载了最新的分支。但是我只有一个 32 位系统。对于 32 位，您只能使用小于 Android 2.3 的 Android 源，对于这些版本，您还必须使用 JDK 5 http://source.android.com/source/building.html

I had same problem. I got it resolved it my changing the file permission for entire android source code folder:
我有同样的问题。我解决了它，我更改了整个 android 源代码文件夹的文件权限：
sudo chmod 755 -R ~/Android

Also had the same problem but it was due to an NTFS issue as I was not able to execute from the partition. Here is the fix I found.
也有同样的问题，但这是由于 NTFS 问题，因为我无法从分区执行。这是我找到的修复程序。

Usually, this is caused by javac is not configured as a alternative for system. So there is no link of /usr/bin/javac for your javac.
通常，这是由于 javac 没有配置为 system 的替代方案造成的。因此，您的 javac 没有 /usr/bin/javac 的链接。
Please setup the alternative for javac using the following command:
请使用以下命令为 javac 设置替代方案：
$ sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.6.0_32/bin/javac" 1
note: the installed directory of javac for me is "/usr/lib/jvm/jdk1.6.0_32/", you can change it by your configuration.
注意：我的javac安装目录是“/usr/lib/jvm/jdk1.6.0_32/”，可以根据自己的配置修改。

I also came across with same situation. I activated root user and logged-in and did the same what is mention at http://source.android.com/source/building.htmlsite and it worked flawlessly.
我也遇到了同样的情况。我激活了 root 用户并登录并执行了http://source.android.com/source/building.html站点上提到的相同操作，并且它完美无缺地工作。
