为什么apt-get install package然后apt-get remove package不消耗并清除几乎一模一样的空间？例如，使用包“latex2html”可以获得：
ubuntu:~$ sudo apt install latex2html
Need to get 758 MB of archives.
After this operation, 1,211 MB of additional disk space will be used.

....
ubuntu:~$ sudo apt remove latex2html
The following packages will be REMOVED:
latex2html
0 upgraded, 0 newly installed, 1 to remove and 92 not upgraded.
After this operation, 5,578 kB disk space will be freed.
