Error "A valid provisioning profile for this executable was not found." when trying to install an app

[ivansavra1]

I get that error when I try to install the ipa both with AltServer and with the AltStore app, the ipa is not the problem, I know it's valid and working since I decrypted it myself from another iPhone, what should I do? I'm not a developer, but it looks like AltStore has a faulty signing mechanism, and is not signing all the libraries included in the .ipa (In this case, BeltUI.framework)
