Description

After updating to fresh iOS 26 I am getting an error message "Unable to Verify App" for every app installed via AltStore, including AltStore itself.
I am also unable to reinstall AltStore using AltServer due to https://github.com/altstoreio/AltStore/issues/1653

What to do?

Research direction

Start by reviewing issue #1653, which blocks reinstalling AltStore with AltServer, then reproduce the “Unable to Verify App” error after updating to iOS 26. The report names no source files or tests; done would require identifying the cause affecting AltStore and installed apps and documenting or implementing a verified resolution.
