如何解决更新时出现“没有名为‘distro_info’的模块”的问题

我正在尝试更新我的 ubuntu 18.04，但是当我尝试运行时sudo do-release-upgrade出现以下错误：

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

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'

我尝试安装 python3-distro-info（已安装且为最新版本）和 python-distro-info，安装后没有任何变化。
我该怎么做才能成功升级？

答案1

sudo apt-get install --reinstall python3-distro-info对我有用。
