当我检查更新时，出现“无法下载存储库信息”错误。

这是详细信息下的内容：

W: Failed to fetch gzip:/var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_natty_main_source_Sources  Hash Sum mismatch, 
E: Some index files failed to download. They have been ignored, or old ones used instead.

我在 ubuntu 16.4 上运行以下命令：

sudo add-apt-repository ppa:noobslab/apps

2 个多月后我打开了 Ubuntu 16.04，现在我收到安装任何软件包的错误（我尝试安装redshift软件包（夜间模式））。

ERROR E: Unable to locate package apt_pkg

我尝试更新 Ubuntu，然后收到错误消息：

W: The repository 'http://ppa.launchpad.net/jonathonf/python-3.6/ubuntu xenial Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.

我可以将 WSL Ubuntu 18.04 上的默认 Python 3.6.5 更改为 3.7 吗？所以，当我检查python3 --version，我得到3.7.x这样我就可以使用该版本与PIP3为好。谢谢

我最近使用以下命令在 Ubuntu 18.04.4 LTS 机器上安装了 python 3.7：

sudo apt-get install python3.7

我还运行了以下命令，因为我希望 python 3.7 运行为python3：

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 1

随后我按照一个建议来运行这个：

sudo apt autoremove

现在，当我尝试启用universe存储库 ( add-apt-repository universe) 时，出现以下错误：

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 28, in <module>
    import apt_pkg
ModuleNotFoundError: No module named 'apt_pkg'

我找到的大多数答案都告诉我python3-apt像这里和这里一样重新安装，但这不起作用。

我还能尝试什么？

编辑：

这里和这里还有一些建议，特别是指向 python 的 …
