遵循以下指示：https://docs.docker.com/install/linux/docker-ce/ubuntu/#install-using-the-repository 我正在尝试在Ubuntu 18.04.02 Server Edition中安装Docker Engine。
首次安装的步骤运行正常，但遇到了以下错误消息：
(base) marco@pc:~$ sudo add-apt-repository \
> "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
> $(lsb_release -cs) \
> stable"
Traceback (most recent call last):
File "/usr/bin/add-apt-repository", line 11, in <module>
from softwareproperties.SoftwareProperties import SoftwareProperties,
shortcut_handler
File "/usr/lib/python3/dist-packages/softwareproperties
/SoftwareProperties.py", line 67, in <module>
from gi.repository import Gio
File "/usr/lib/python3/dist-packages/gi/__init__.py", line 42, in
<module>
from . import _gi
ImportError: cannot import name '_gi' from 'gi' (/usr/lib/python3/dist-
packages/gi/__init__.py)
但是在python3中导入gi可以正常工作：
(base) marco@pc:~$ python3
Python 3.7.3 (default, Mar 27 2019, 22:11:17)
[GCC 7.3.0] :: Anaconda, Inc. on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import gi
>>>
已解决：
由于@ Smurfz87，我发现python3.7.3版本导致apt-repository出现此问题。更改/ usr / bin / add-apt-repository的第一行以指向3.6版本后：＃！/ usr / bin / python3.6一切正常：
(base) marco@pc:~$ sudo add-apt-repository \
> "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
> $(lsb_release -cs) \
> stable"
