这是一个可怕的错误
Installation failed with message Failed to finalize session : INSTALL_FAILED_USER_RESTRICTED: Install canceled by user.
It is possible that this issue is resolved by uninstalling an existing version of the `apk` if it is present, and then re-installing.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?

MIUI优化关闭 打开USB调试 通过打开USB验证应用程序
注意:当通过USB打开安装时，会弹出提示“设备暂时受限”
当前回答
从开发人员选项中关闭MIUI优化 安装app 把它打开。
下次安装这个apk(和它的更新)不会再给出这个错误。

If above answer didn't work for you as it didn't work for me on my Xiaomi Mi5.I tried to figure out the Core reason behind it and solve it. In MIUI, in order to change "Install via USB" option, you must be connected to the internet and signed in your Mi account. Due to some reason, requests from out of the China servers are getting rejected, so I connected to one open China VPN and tried again to enable 'Install via USB' and I got success.

什么对我有用
goto设置->附加设置->开发人员选项->撤销USB调试授权。 在任务管理器中关闭adb.exe (CTRL + SHIFT + ESCAPE) 重新安装，观察弹出窗口(接受RSA签名并安装) 现在一切都好了
要打开“通过USB安装”和“USB调试(安全更改)”，需要登录到小米帐户，然后这两个可以打开，并与红米作为开发人员一起工作
注意:当打开USB调试(安全更改)时，会弹出一些安全警报，所有安全警报都需要接受才能在开发人员模式下工作
失败[INSTALL_FAILED_USER_RESTRICTED: Install cancelled by user]:
进入设置->附加设置->开发人员选项->开发人员选项(需要启用)->USB调试(需要启用)->通过USB安装(需要启用)->USB调试(安全设置)(需要启用)
在上述步骤中完美地工作。
享受你的编码……
