由于未满足依赖关系，无法安装libsdl2-dev。

Question

我正在运行Ubuntu16.04，我试图安装libsdl2-dev，但没有成功。我已经搜索了谷歌，并在这个网站上跟踪了几个答案，等等。我试着将我的存储库简化为仅仅安全的存储库，运行了apt-获取更新，apt-get升级。还有很多其他的事情我现在都记不起来了。我试过了在谷歌上找到的所有东西。这是我得到的输出

sudo apt-get -f install libsdl2-dev

我也试过

y-ppa-manager

和

synaptic

当我尝试使用synaptic安装libsdl2-dev时，首先没有坏包，但是当我标记libsdl2-dev安装时，它说我必须首先删除损坏的包。我尝试过apt-获取、删除--清除libsdl2-dev，但是由于它没有安装，所以不能删除。

我感谢所有的帮助。谢谢。我是post输出您给我的命令，并将保持活跃的这个问题，直到它可以解决。再次感谢你

最后编辑：

这个问题现在已经解决了。我的解决方案的最终步骤是启用异种安全和异种更新回购。在我这样做之后，尝试了sudo After更新和sudo After升级，我在下载一些更新时遇到了错误。在此之后，我将下载服务器更改为主服务器，并重新运行更新和升级，成功地完成了更新和升级。在此之后，我成功地安装了libsdl2-dev。感谢道格和ali76的帮助！

Answer 1

不要尝试以下命令：

sudo apt-get install 229-4 ubuntu6 E:无法找到包229-4 ubuntu6

因为在存储库中没有任何带有229-4ubuntu6名称的包。

apt输出显示

libudev1 (= 229-4ubuntu4)，但要安装229-4ubuntu 6

这意味着，229-4ubuntu6版本的libudev1已经安装，但229-4ubuntu4版本是必需的。

其他的事情是，libudev1 for xenial的最后一个版本是229-4ubuntu17，但是您的apt返回的最后一个版本是229-4ubuntu6。发生此问题的原因是，许多Ubuntu的存储库在您的系统上被禁用，并且您的存储库没有更新。

因此，作为第一步，我们尝试使用以下命令启用所有Ubuntu存储库：

sudo add-apt-repository main
sudo add-apt-repository universe
sudo add-apt-repository restricted
sudo add-apt-repository multiverse

然后更新您的存储库和包：

sudo apt update
sudo apt upgrade

然后尝试修复破损的包：

sudo apt -f install

在最后一步中，尝试安装libsdl2-dev包：

sudo apt install libsdl2-dev

更新:请将这一行添加到您的/etc/apt/sources.list文件中：

deb http://archive.ubuntu.com/ubuntu xenial universe multiverse
deb-src http://archive.ubuntu.com/ubuntu xenial universe multiverse

deb http://us.archive.ubuntu.com/ubuntu/ xenial universe
deb-src http://us.archive.ubuntu.com/ubuntu/ xenial universe
deb http://us.archive.ubuntu.com/ubuntu/ xenial-updates universe
deb-src http://us.archive.ubuntu.com/ubuntu/ xenial-updates universe

deb http://us.archive.ubuntu.com/ubuntu/ xenial multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ xenial multiverse
deb http://us.archive.ubuntu.com/ubuntu/ xenial-updates multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ xenial-updates multiverse

deb http://security.ubuntu.com/ubuntu xenial-security universe
deb-src http://security.ubuntu.com/ubuntu xenial-security universe
deb http://security.ubuntu.com/ubuntu xenial-security multiverse
deb-src http://security.ubuntu.com/ubuntu xenial-security multiverse

并评论这句话：

deb http://ftp.belnet.be/ubuntu.com/ubuntu/ xenial multiverse restricted universe main
deb-src http://ftp.belnet.be/ubuntu.com/ubuntu/ xenial multiverse restricted universe main #Added by software-properties

然后尝试使用以下命令更新存储库和包：

sudo apt update
sudo apt upgrade

然后再试着安装：

sudo apt install libsdl2-dev
