我尝试将我的 Ubuntu 13.04 升级到 13.10，但升级 latex 包失败，错误来自 [此处] (从 13.04 升级至 13.10 停止) 并冷静下来尝试回滚。但是计算机声称处于 13.10。
当我尝试运行时，apt-get install我得到：
Reading package lists... Done

Reading state information... Done
You might want to run 'apt-get -f install' to correct these.

我考虑过删除重新下载的提升功能，但不想让我的系统变得更奇怪和更不稳定。
关于如何最好地解决此问题以及升级失败可能导致的任何其他问题，您有什么建议吗？
答案1
问题是libboost1.49-dev从其他存储库安装的版本与libboost1.49-dev从主存储库新安装的版本相竞争。
因此，首先您需要删除礼物libboost1.49-dev。
sudo dpkg --purge libboost1.49-dev
然后清理 apt-cache
sudo apt-get clean
然后运行sudo apt-get -f install。
