我上周刚刚安装了 Ubuntu 18.04，这意味着我没有从 16.04 升级，而是格式化了硬盘并安装了 18.04。
我正在尝试安装texlive-full，但每当我使用时：
sudo apt install texlive-full
这是我得到的：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

在聊天过程中我们发现 OP 有来自JonathonF 的 PPA：
$ dpkg -l | grep york
ii libkpathsea6:amd64 2018.20180129.46472-0york1~16.04 amd64 TeX Live: path search library for TeX (runtime part
我们删除了这个包
sudo apt purge libkpathsea6
然后安装TeXLive
sudo apt install texlive-full

我遇到过类似的问题，删除旧软件包 libsynctex1 帮助我解决了这个问题。删除之前忘记检查我安装了哪个版本
sudo apt purge libsynctex1
sudo apt install texlive-full
