无法应用macbuntu主题

Question

我刚刚开始使用Ubuntu，所以请给我一个解释的答案。

我试图在我的Ubuntu16.10中安装macbuntu主题。我做了第一步

sudo add-apt-repository ppa:noobslab/macbuntu

这一步效果很好。下一次我做的时候，

sudo apt-get update

我得到了错误

W: The repository 'http://ppa.launchpad.net/docky-core/stable/ubuntu yakkety Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://ppa.launchpad.net/docky-core/stable/ubuntu/dists/yakkety/main/binary-amd64/Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

这仅仅是导致错误的最后几行。

我该怎么解决这个问题？

编辑:这是sources.list.d目录的内容

    docky-core-ubuntu-stable-yakkety.list
    docky-core-ubuntu-stable-yakkety.list.save
    noobslab-ubuntu-macbuntu-yakkety.list
    noobslab-ubuntu-macbuntu-yakkety.list.save
    webupd8team-ubuntu-java-yakkety.list
    webupd8team-ubuntu-java-yakkety.list.save
    webupd8team-ubuntu-sublime-text-3-yakkety.list
    webupd8team-ubuntu-sublime-text-3-yakkety.list.save

lsb_release -a command输出

    No LSB modules are available.
    Distributor ID: Ubuntu
    Description:    Ubuntu 16.10
    Release:    16.10
    Codename:   yakkety

Answer 1

按照步骤

 cd /etc/apt/sources.list.d/

 sudo -H gedit noobslab-ubuntu-macbuntu-yakkety.list

文件将打开，第一行如下所示

deb http://ppa.launchpad.net/noobslab/macbuntu/ubuntu yakkety main

将yakkety替换为xenial，使这一行变为

deb http://ppa.launchpad.net/noobslab/macbuntu/ubuntu xenial main

保存并退出文件，然后

sudo apt-get update

现在尝试使用此mac theme安装回答

删除mac主题的

：

如果系统不支持安装mac主题，请使用以下方法卸载：

sudo apt-get install ppa-purge
sudo ppa-purge ppa:noobslab/macbuntu
sudo apt-get update

或

sudo apt-add-repository remove ppa:noobslab/macbuntu
