I've gotten the same error before a lot of times. I've never been able to refresh AltStore on my iPhone 8 wirelessly from my Windows 10 PC, so I have to connect.

I was just getting your problem with installing unc0ver, but after a few times, I got it to work while connected (after trying both wirelessly and connected multiple times). I'm still gonna keep an eye on this thread because I get the same error time and time again.

You guys need to implement error logging - it would help us troubleshoot errors and it would help you to squash bugs

Closing issue. Bug seems to have been fixed. anyway, i think it was caused by a corrupted or broken .ipa because iOSAppSigner on mac threw an error with it too.

Was AltStore the broken IPA, or the IPA you were trying to install?
