python-安装sublime遇到异常

(base) gs@ubuntu16:~$ sudo snap install sublime-text
error: This revision of snap "sublime-text" was published using classic confinement and thus may
       perform arbitrary system changes outside of the security sandbox that snaps are usually
       confined to, which may put your system at risk.

       If you understand and want to proceed repeat the command including --classic.

这中异常该如何解决呢？，其实很简单。。。

(base) gs@ubuntu16:~$ sudo snap install sublime-text --classic
Download snap "core" (8039) from channel "stable"                     31%  146kB/s 7m25s

正常安装了。。。
