1 The context
=============
I had previously installed the package `rime-data'. One of the files
that is installed by that package is called `wubi86.dict.yaml'.
I'm currently experimenting with `ibus' and I need all files that
exist in `/gnu/store' that are called `wubi86.dict.yaml' to be deleted
from my system. I've located those files, but when I try to delete
those files, I get the following error
,----
| guix gc -D /gnu/store/252h4ryvdj3d3bgnm1v47s7838wn86nz-profile
`----
,----
| finding garbage collector roots...
| guix gc: error: cannot delete path
`/gnu/store/252h4ryvdj3d3bgnm1v47s7838wn86nz-profile' since it is still
alive
`----
See next section to see what I've tried to delete those directories.
2 What I've tried
=================
I know how to locate all files that are called `wubi86,dict.yaml' and
are located under `/gnu/store'
,----
| sudo updatedb
`----
,----
| locate 'wubi86.dict.yaml'
`----
,----

/gnu/store/zj0cf20jk3qgl12451znx1n8rj13z2jg-profile/share/rime-data/wubi86.dict.yaml

the same error (please see code blocks below)

3 Additional information
========================
I found [this thread] in the help-guix mailing list on the same
topic. In [this reply], someone mentions that it is possible to list
the referrers to see which directories are pointing to those
directories. This is the output of those command.
For the two directories that end in `*-profile', `guix gc --referrers'
print the directory itself.

For the directory, that has the files from the package, a lot of files
ending with `drv' is shown.

4 The question
==============
How can I get rid of those three directories in `/gnu/store/' [1] so
that I can make sure that my system has no file called
`wubi86.dict.yaml'?
[1] Namely
+ `/gnu/store/252h4ryvdj3d3bgnm1v47s7838wn86nz-profile'
+ `/gnu/store/b3f1s6nnj1rg7szcmb3n3y194ayhfgja-rime-data-0.38.20210802'
+ `/gnu/store/zj0cf20jk3qgl12451znx1n8rj13z2jg-profile'

First of all, you don't need to delete these files. Even if they exist in the store, they won't be foumd by other software unless they are currently installed in one of your profiles.
The error you get when you try to delete them means that one of the generations of one of your profiles still has a reference to them. You should have a look at the symlinks at /var/guix/profiles to fehure out which profile and which generetion that is.

For listing all your profiles, you can run:
guix package --list-profiles
Well, you could run something like:
for p in $(guix package --list-profiles);
do
echo $p;
guix package -p $p --list-generations | grep rime-data
;done
so you will find in which profile you installed and removed the package
rime-data. Then, ’guix package -p path/to/that/profile -l’ will list
all the generations. Depending on context, you can delete the
generations containing the package rime-data; see “guix package
--delete-generations”.
Last, “guix gc -D” should work as expected.
Please note that the corollary of your annoyance is that you are still
able to switch to a specific generation of some profile containing the
package ’rime-data’ without doing anything more (download or else).
Cheers,
simon
