[Bug] uYou download: filesystem permission error when using Apple Development Certificate to sign IPA (error 200)

[danielnma]

Device info

• Devices: iPad 2020 on iPadOS 15.1.1 and iPhone X on iOS 15.5
• uYouPlus: 16.42.3_2.1
• Xcode with iOS App Signer

Describe the bug

The bug is as described in the FAQ: "Error 200: Unable to move a file from…" (link)

How to reproduce the bug

Resign the IPA using iOS App Signer and install:

1. Choose a valid and current Apple Development Certificate
2. Use a wildcard iOS Team Provisioning Profile
3. Do not change the Application ID, Display Name, or version
4. Install the resigned IPA onto any registered iPadOS/iOS device with Xcode's device manager
5. Experience the bug

Additional context:

The FAQ suggests this is because the user used an Apple Distribution Certificate instead of an Apple Development Certificate. This is not the case as can be seen in the steps to reproduce the bug. I am a current Apple Developer.

That’s interesting 🤔 can you try using the apple development certificate with an explicit profile?

Same here,

I followed the FAQ (set the Identity type to use for appdb PRO to Development), however it still results in the same error (200).

the same issue (Error 200) appears when using dev cert with SignTools.

it does not happen when using uYou on a jailbroken device.

Will there ever be a fix for this download error 200 problem?

Installing it with TrollStore fixes it, but this isn't for everyone

Strangely, signing the app with Sideloadly fixes the download issue (Local Anisette mode).

These are the results of my testing:

• Downloading works on jailbroken devices with the official tweak. ✅
• Downloading does not work with distribution certificates using SignTools. ❌
• Downloading does not work with development certificates & wildcard provisioning profile using iOS App Signer. ❌
• Downloading does not work with distribution certificates & wildcard provisioning profile using iOS App Signer. ❌
• Downloading works with development certificates & explicit provisioning profile using iOS App Signer. ✅
• Downloading works with distribution certificates & explicit provisioning profile using iOS App Signer. ✅
• Downloading works with Normal accounts using Anisette in Sideloadly. ✅
• Downloading works with Developer accounts using Anisette in Sideloadly (Development certificate + explicit profile). ✅
• Downloading works with TrollStore. ✅

you were right, explicit profiles work.

[Aholicknight]

you were right, explicit profiles work.

Do you use Signulous? I have Signulous to sign IPAs and have no idea how to export or generate a explicit profile

[Mikasa-san]

Is there any fix ?

[mapeles]

I believe this issue is also related to #335.

[elisaado]

Using an explicit profile works for me as well, that does however replace any app already installed with that profile which makes it an unfavourable option.

Hello, I have a question. Is it possible to change the download location or the location when accessing the downloaded file? In what line of code can I see this?
Actually it is possible to fix notifications and downloads with a developer account but you have to change the location when you want to access the bundle uyou @qnblackcat ?

Not possible. Please ask the dev of uYou instead
