我有 kivy 1.10.1，python 3.8.2，我在 Ubuntu20.04 上编码。当我启动我的小程序时，我收到此错误：

    [CRITICAL] [Cutbuffer   ] Unable to find any valuable Cutbuffer provider.

  File "/usr/lib/python3/dist-packages/kivy/core/__init__.py", line 55, in core_select_lib

The solution is just to install xclip with this command:

sudo apt-get install xclip
