这里稍微详细一点。我在 Termux 上运行 Ubuntu，安装后可以正常使用。但过了一会儿，这个就出现了。我尝试了在 Google 上能找到的所有方法，也尝试了一些自己的想法。这阻止了我更新和升级或安装 GitHub 上的东西，比如 sherlock，但我无法使用它，因为我需要安装 python-pip，但当我尝试安装任何东西时，我都会收到此错误消息。

我真的不明白这个问题，因为什么都不起作用

Termux 适用于 Android 5.0 或更高版本，但以下是Termux wiki 常见问题解答。
On recent Android versions, the write access to the external SD card is done over Storage Access Framework. It is not possible to provide it's API to the command line programs.
There several solutions:
Use root for putting necessary files to external SD.
Use custom ROMs. Some of them have disabled SD card access restriction, so you can freely access your external SD card.
Use a Termux private directory on the external SD card. Usually, it's path should be /storage/XXXX-XXXX/Android/data/com.termux.
Termux only has a few packages. Can I use the Debian repositories instead?
No, you can't.
There are major differences between Termux and regular Linux distributions, and packages from these repositories won't work. See Differences from Linux for more information.
考虑到所有这些因素，你无法在 Termux 上更新 Ubuntu 软件包也就不足为奇了，因为在 Ubuntu 下更新软件包需要 root 权限，而且促卵泡激素在 Termux 下没有遵循，Ubuntu 软件包系统无法将东西放在需要的地方。
可以通过使用prootTermux 来解决这个问题，但由于 AskUbuntu 是一个专注于 Ubuntu 的网站，因此在我们的姊妹网站上回答有关 Termux 的问题可能会得到更好的结果https://android.stackexchange.com/或者通过查看Termux 维基
