Errata on other scientist's work

U. Dudley, A Guide to Elementary Number Theory, MAA Guide #5, 2009
A nice book with an unfortunate amount of typos and oversights. In many theorems the necessary assumptions are not mentioned, and there is a wrong proof inside as well. I did not manage to contact Dudley directly, and after sending a list of errata to the publisher in late 2017, they stopped communicating with me. It has been almost a year, so I decided to put the list here.
