软件包已安装但未检测到。（毕业）

  • 772

我通过典型方式安装了 gradle：

sudo apt install gradle
Reading package lists... Done
Building dependency tree       
Reading state information... Done
gradle is already the newest version (3.5-0ubuntu1).
0 to upgrade, 0 to newly install, 0 to remove and 8 not to upgrade.

接下来我想使用这个程序： 

$ gradle 
The program 'gradle' is currently not installed. You can install it by typing:
sudo apt install gradle

我试图删除 java，清除 gradle，从任何地方删除它并重新安装。没有任何帮助......最令人困惑的是，这个包几天前可以正常工作，没有任何问题。

下面是一些调试：

$ which gradle
$ whereis gradle
gradle:
$ apt-cache policy gradle
gradle:
  Installed: 3.5-0ubuntu1
  Candidate: 3.5-0ubuntu1
  Version table:
 *** 3.5-0ubuntu1 500
        500 http://ppa.launchpad.net/cwchien/gradle/ubuntu xenial/main amd64 Packages
        500 http://ppa.launchpad.net/cwchien/gradle/ubuntu xenial/main i386 Packages
        100 /var/lib/dpkg/status

        500 http://archive.ubuntu.com/ubuntu xenial/universe i386 Packages
     1.4-2ubuntu1 500
        500 http://us.archive.ubuntu.com/ubuntu trusty/universe amd64 Packages
        500 http://us.archive.ubuntu.com/ubuntu trusty/universe i386 Packages

当正确检测到这个包时，如何将系统恢复到状态？

更新

我找到了命令：

sudo apt-get clean

现在我得到：

sudo apt install gradle

    最后感谢@muru 的评论，我完成了以下步骤：

    我删除了ppa:cwchien/gradle：

    sudo rm -rf /etc/apt/sources.list.d/cwchien-ubuntu-gradle-xenial.*
sudo apt-get update

    我从官方仓库安装了旧的 gradle：

    sudo apt-get install gradle

    然后正确安装了所有依赖项。然后我再次追加cwchien-ubuntu-gradle-xenial并再次安装：

    sudo apt-get install gradle-ppa gradle

    最后在网站https://gradle.org/install我找到了命令：

    export PATH=$PATH:/opt/gradle/gradle-3.5/bin

    这终于解决了我的问题，现在：

    gradle -v

------------------------------------------------------------
Gradle 3.5
------------------------------------------------------------

    更新

    现在我通过sdkman.io通过这些命令安装 gradle：

    安装 sdkman

    curl -s "https://get.sdkman.io" | bash

    安装 gradle

    sdk install gradle 4.0.2
