Re-download/update AltStore to fix this.

ok, so I reinstalled it. with my original apple id, I clicked on the installation for my phone, then it came up with "AltStore already installed on another device.". I clicked continue but then got another error. "The operation couldn’t be completed. (NSURLErrorDomain error -1011.)", I retried the installation and then got the "no matching provisioning file" error.

Having problems here to. Could be altstore 1.4 update problem?

I was having the problem.
But I search for updates, then update AltServer.
After this I could reinstall on my phone.

SOLVED: I switched to the windows version and it worked. I assume there was a problem with my mac rather than altserver itself.

Try to trust the phone with your Mac

I fixed this issue by installing an updated version of AltServer on my Mac (and dragging the .app into the Applications folder), then uninstalling AltStore on my phone and reinstalling using AltServer.

I see that error and I cant install newest version (1.4.1) with mac os Big Sur. How I can install AltStore in my phone ?

I could not solve it with the solutions mentioned so far.

I had the error above.
On my computer: I updated AltStore & restarted.
On my device: I deleted AltStore and its certification, then reinstalled & re-trusted it.
Thankfully, updating to AltStore 1.4 made the above error go away and I was able to complete this installation process.
However, despite all this, the AltStore app still crashes when opened.

Any idea what to do? I followed the installation process so it seems like a bug.

Windows 10, latest AltServer (1.4), iPhone XR, iOS 13.3.1
