This is on Ubuntu 22.10 x86-64, with current Emacs master (commit 
8a49a888532c955ae81855636a65b446508cb361 dated today). "make check" 
fails in several of the package-test tests. Some package-test expertise 
(which I don't have) would be of use in debugging this.

I'm attaching a copy of the build log (created with ./autogen.sh; 
configure; make; make check) and of the test failure logged in 
test/lisp/emacs-lisp/package-tests.log. The build log is the same as in 
Bug#59061.
