[beginner's question] What is preventing my package from being deleted?

[Rodrigo Morales]

I defined a package and I installed it. Now, I'm trying to delete that package, but the following error is shown:

#+HEADER: :prologue "exec 2>&1"
#+HEADER: :epilogue ":"
#+BEGIN_SRC sh
guix gc -D /gnu/store/r7l2scg74yd6pryrs2xbh268akhwl7qi-font-stkaiti-287399335ec1beb72062ce67c36eaa8bec35f386 ; echo Exit code: $?
#+END_SRC

Exit code: 1
#+end_example

I have listed all referrers, but no referrer is shown.

#+HEADER: :prologue "exec 2>&1"
#+HEADER: :epilogue ":"
#+BEGIN_SRC sh
guix gc --referrers /gnu/store/r7l2scg74yd6pryrs2xbh268akhwl7qi-font-stkaiti-287399335ec1beb72062ce67c36eaa8bec35f386 ; echo Exit code: $?
#+END_SRC

#+RESULTS:

#+end_example

My question is: If there are no referres, then what is preventing that package from being deleted using =guix gc -D=?

Did you remove the package with =guix remove=?

I never installed it using "guix package -i". I installed that package
using "guix home reconfigure", so if I try to use "guix remove", the
following error is reported:

#+BEGIN_SRC text
$ guix remove /gnu/store/r7l2scg74yd6pryrs2xbh268akhwl7qi-font-stkaiti-287399335ec1beb72062ce67c36eaa8bec35f386  ; echo Exit code: $?
guix remove: error: package '/gnu/store/r7l2scg74yd6pryrs2xbh268akhwl7qi-font-stkaiti-287399335ec1beb72062ce67c36eaa8bec35f386' not found in profile
Exit code: 1

Then the package is locked in the /gnu/store until you remove the
package from your configuration, reconfigure it and follow up with =guix
home delete-generations <pattern> ; guix gc -d <pattern>=.

Here is how I deal with my configurations by usage of bash aliases:
~
$ alias
alias collect-garbage='guix home delete-generations 7d ; sudo guix system delete-generations 7d ; sudo guix gc -d 7d'
alias pull-guix='guix pull'
alias reconfigure-system='sudo guix system reconfigure -e '\''(@ (systems ayase) operating-system*)'\'''
alias update-system='guix pull ; sudo guix system reconfigure -e '\''(@ (systems ayase) operating-system*)'\'' ; guix home delete-generations 7d ; sudo guix system delete-generations 7d ; sudo guix gc -d 7d'
~
My home configuration is declared as a system service, which is why it
is not explicitly managed in the aliases.
