This is what I get:

manuel@hathaway:~$ emacs -batch -l comp -f batch-native-compile 
/usr/local/share/emacs/28.0.50/lisp/time.el.gz
uncompressing time.el.gz...
uncompressing time.el.gz...done
Debugger entered--Lisp error: (file-error 
"/usr/local/share/emacs/28.0.50/lisp/time.el.gz" "Opening output file" "Cannot 
overwrite file" "/usr/local/share/emacs/28.0.50/lisp/time.elc")
  signal(file-error ("/usr/local/share/emacs/28.0.50/lisp/time.el.gz" "Opening

"/usr/local/share/emacs/28.0.50/lisp/time.el.gz"))

This is using sudo to invoke the same command:

manuel@hathaway:~$ sudo emacs -batch -l comp -f batch-native-compile 
/usr/local/share/emacs/28.0.50/lisp/time.el.gz
[sudo] password for manuel:
uncompressing time.el.gz...
uncompressing time.el.gz...done
uncompressing time.el.gz...
uncompressing time.el.gz...done
