平台：Ubuntu 17.04服务器
ubuntu17.04服务器安装包括python2.7和python3.5，我从源代码手动安装了python3.6.3，但是lsb_release -a失败了：

root@birds:~# lsb_release -a
Traceback (most recent call last):
  File "/usr/bin/lsb_release", line 25, in <module>
    import lsb_release
ModuleNotFoundError: No module named 'lsb_release'

但是如果我修改文件lsb_release的第一行
#!/usr/bin/python3 -Es到#!/usr/bin/python3.5 -Es它又工作了。

root@birds:~# lsb_release -a
LSB Version:    core-9.20160110ubuntu5-amd64:core-9.20160110ubuntu5-noarch:security-9.20160110ubuntu5-amd64:security-9.20160110ubuntu5-noarch
Distributor ID: Ubuntu
Description:    Ubuntu 17.04
Release:    17.04
Codename:   zesty

以下是模块搜索路径：
Python3.5

root@birds:~# python3.5

>>> import lsb_release

>>> exit()

Python3

root@birds:~# python3

>>> import lsb_release
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'lsb_release'

>>> exit()

有人知道怎么修吗？谢谢。

- 解决方案：**

sudo ln -s /usr/share/pyshared/lsb_release.py /usr/local/lib/python3.6/site-packages/lsb_release.py

- 解释：**

我们可以看到/usr/bin/lsb_release

#!/usr/bin/python3 -Es

import lsb_release

关键步骤是import lsb_release，但问题是Python 3.6没有这个模块。
因此，您必须将python3从python3.5覆盖为python3.6。这就是lsb_release损坏的原因。
为了验证它，我们可以在python3.6中看到：

➜  ~ python3.6 
Python 3.6.4 (default, Feb  6 2018, 16:57:12) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import lsb_release
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'lsb_release'

则在python3.5中：

➜  ~ python3.5
Python 3.5.2 (default, Nov 23 2017, 16:37:01) 
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import lsb_release
>>> lsb_release.__file__
'/usr/lib/python3/dist-packages/lsb_release.py'

此文件在哪里：

➜  ~ ll /usr/lib/python3/dist-packages/lsb_release.py
lrwxrwxrwx 1 root root 38 Jul   7  2016 /usr/lib/python3/dist-packages/lsb_release.py -> ../../../share/pyshared/lsb_release.py

所以，这个模块lsb_release存在于python3.5中，而不存在于python3.6中，我们最终找到了它!
现在，让我们通过添加到原始lsb_release.py文件的链接来修复它!
对我有用!

当dist-packages被清除或者python安装无法访问时，就会发生这种情况。
当我在/usr/lib/python3中删除一个dist-packages/时，我遇到了这个问题-因为有一些用户安装的包与我的本地包冲突。
要修复，您可以尝试：
sudo apt reinstall lsb-release
这为我修正了这个问题。它也避免了清除lsb-release的兄弟答案的问题。不需要。

我在树莓派上的python 3. 6和python 3. 7也遇到过同样的问题，但我认为它在任何地方都能工作。
唯一像符咒一样工作的是将lsb_release移动到备份文件中。

sudo mv /usr/bin/lsb_release /usr/bin/lsb_release_back

你只需清除现有的lsb版本并重新安装它，它将解决你的问题。

$ sudo apt purge lsb-release
$ sudo apt install lsb-release
