Why can't i update my j1 ace?

[Android Central Question]

I want to update my software but it keeps telling me that my phone has been modified in an unauthorized way

Since your phone was released in 2015, Samsung have discontinued its software updates on that device since newer software such as nougat will not run due to your phone only having 1gb of ram, Your phone is locked to Android Kitkat
