IPA file cannot be installed

[alias38]

Hello, when I download the ipa, the installation package is smaller than the appstore's and cannot be installed.

Please provide more information. Where are you trying to install the ipa package? App size is irrelevant compared to what you see in the App Store app.

I tried to install using alist, but it failed to install

There is no problem with alist installation. When using software downloaded from AppStore

ipatool downloads unedited/encrypted ipas from Apple servers.

To install the downloaded file, you need to decrypt the ipa via a jailbroken device.

There should be no need to jailbreak, after all, you have logged into the AppStore account

I'm not sure, you can check @Lakr233's implementation here: https://github.com/Lakr233/Asspp

This issue occurs because the method used by ipatool to inject the signature is not supported by installd. You can unpack the IPA file using an alternative zip tool and then repack it.

Maybe #434 will fix it:

The installation failure was caused by the generated IPA not being compatible
iOS streaming unzip (StreamingUnzip), which is required by itms-services installation.
