Thanks for the reply. The problem I encountered is that guix shows a list of 
packages
to be upgraded, but didn't upgrade them as it should.

I just found out that the problem was caused by missing packages definitions. I
installed a few software packaged myself using `guix package -f ...` but didn't
 add the recipes to GUIX_PACKAGE_PATH.

Then Guix failed to upgrade any other packages from official repo(and report 
false
upgrade list). After exporting GUIX_PACKAGE_PATH, problem was resolved.
I should have thought of it earlier. But maybe this can be added to the doc?
