The issue is from several layers; (search-path %load-path file) returns
#false.  See:

 1. package-field-location from (guix packages)
    called by update-package-source from (guix upstream)

 2. update-package-source from (guix upstream)
    called by package-update from same module
    called by update-package from (guix scripts refresh)

The issue looks similar as #66901 [1].  Well, I have tried to improve
the situation by setting some ’canonicalize-path’ here or there.
However, then the next issue is from the call ’(absolute-location loc)’
in ’update-package-source’ from module (guix upstream); it returns:

Hum, it needs to be investigated…
