我尝试了网上找到的很多教程，但无法安装 Skype。
apt-get 给了我这个错误:(但 Synaptic 没有报告任何损坏的包）
Some packages could not be installed. This may mean that you have

但这些解决方案都不起作用。有人能帮助我吗？
答案1
根据版本号，您最有可能使用的是xorg-edgersPPA（或者至少使用该 PPA 中的软件包）。
理论上，apt如果你添加了该 PPA，应该会同时获得 amd64 和 i386 版本。要确定你是否添加了 PPA，请运行apt-cache policy libdrm-intel1。如果带有版本号的条目2.4.54+git20140523.8fc62ca8-0ubuntu0ricotz~trusty没有指向 PPA 的链接（有仅有的 100 /var/lib/dpkg/status而不是500某样东西），那么您就没有使用 PPA。
如果您没有使用 PPA（即使您没有使用 PPA 并且想要安全地摆脱这些软件包），请运行sudo add-apt-repository ppa:xorg-edgers/ppa然后sudo apt-get update然后sudo apt-get dist-upgrade。
如果您不想使用 PPA（并且想要摆脱 PPA 中的软件包），或者您正在使用 PPA 并且无法安装 Skype，请运行sudo ppa-purge xorg-edgers。
按照此操作后，尝试安装 Skype。

我昨天也遇到了同样的问题。真是痛苦。是的，痛苦的就是我。
以下是我解决这个问题的方法：
dpkg --add-architechture i386
apt-get update
apt-get upgrade
apt-get dist-upgrade
apt-get install skype
