如何解决更新中“没有模块名为'distro_info'”的问题

Question

我正在尝试更新我的ubuntu18.04，但是当我试图运行sudo do-release-upgrade时，我得到了以下错误：

Checking for a new Ubuntu release
Get:1 Upgrade tool signature [1.554 B]

    (result, consumed) = self._buffer_decode(data, self.errors, final)

Original exception was:

  File "/tmp/ubuntu-release-upgrader-qvik6xoe/disco", line 8, in <module>
    sys.exit(main())
  File "/tmp/ubuntu-release-upgrader-qvik6xoe/DistUpgrade/DistUpgradeMain.py", line 224, in main

    import distro_info
ModuleNotFoundError: No module named 'distro_info'

我试着安装python 3发行版-info(已经安装并更新)和python-分发版-信息，但我安装了，但什么都没有改变。

我怎样才能成功地升级？

sudo apt-get install --reinstall python3-distro-info为我工作。
