我知道这个问题已经被问过好几次了，但是所有建议的修复方法都对我没用。我将提供我尝试运行的一些过程的输出。
我很想得到帮助来解决这个问题。我得到了朋友的帮助，但他们无法解决这个问题，而且我已经花了超过 4 小时的时间。我非常感谢他们的帮助。
我在以下软件包中遇到此错误：
* libtxc-dxtn-s2tc0:i386
* libgl1-mesa-glx:i386
有证据表明它们是依赖性错误，但我在这方面没有取得进展。我的想法是，我有软件包
libgl1-mesa-glx:i386
libgl1-mesa-glx:amd64
，这可能会导致问题，但我毫无头绪。
我尝试发布很多可能有助于他人帮助我的内容，但如果需要更多信息，请询问。
（背景）我的联想 Legion Y520 运行 ubuntu 16.04 已有数月（自购买以来）。三天前，它没电了。昨天，当我给它充电时，它根本无法正常开机。我启动了恢复模式，但只能通过终端访问它，因为我陷入了登录问题循环。我花了一些时间，但我得到了图形驱动程序，一切（除了这个问题）都恢复正常了。在此过程中我注意到了这个问题。我 100% 确定在电池耗尽之前不是这种情况。这是我第一次收到此错误。
dpkg——审计
The following packages are only half configured, probably due to problems
configuring them the first time. The configuration should be retried using
dpkg --configure <package> or the configure menu option in dselect:
libgl1-mesa-glx:i386 free implementation of the OpenGL API -- GLX runtime
libtxc-dxtn-s2tc0:i386 Texture compression library for Mesa

答案1
我解决了我的问题。我正在发布答案，但如果有人要求，我可以删除问题 - 因为我是新手，不知道正确的做法。
这是替代方案的问题（如警告所示）。以下这我能够消除这个错误。
我的步骤：
update-alternatives --remove-all libtxc-dxtn-i386-linux-gnu
rm -f /var/lib/dpkg/alternatives/libtxc-dxtn-i386-linux-gnu
update-alternatives --remove-all i386-linux-gnu_gl_conf
rm -f /etc/alternatives/i386-linux-gnu_gl_conf
之后我运行了
apt-get -f install，这是第一次成功
apt-get update失败了，但我可以调查......
