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
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:

你系统上的这个libxml2版本不对导致 libxml2-dev 没安装上
可以dpkg --force-all -P libxml2 强制卸载
然后apt-get install libxml2 libxml2-dev 后再看看libxml2能否正常安装上

执行dpkg -r libxml2命令后出现这个，正常吗？

再执行apt-get install libxml2 libxml2-dev后还是出现这个提示

可以尝试 dpkg --force-all -P libxml2 强制卸载后再按2楼方式安装libxml2
