Probably with TRAMP: https://www.emacswiki.org/emacs/TrampMode#toc20

AFAICT, this is essentially the problem described in #24643 and should be
fixed by the suggestion there:

Subject: [PATCH v1] Don't call package--ensure-init-file if initialized during
 startup

* lisp/emacs-lisp/package.el (package-initialize): Check
`after-init-time' rather than `load-file-name' to decide if
`package--ensure-init-file' should be called.  Depending on
`load-file-name' will fail if the user calls `pacakge-initialize' in
file which is loaded from the init file (Bug#24643, Bug#25819).
