guix package conflict

[Andy Tai]

Hi, on my Fedora system running guix as guix on a foreign distribution, I
run into this:

guix package: error: profile contains conflicting entries for cairo
guix package: error:   first entry: cairo@1.16.0
/gnu/store/4d8rc6vjkhsk1b20rigz0nzl7zffn4b5-cairo-1.16.0
guix package: error:    ... propagated from python-pycairo@1.17.1
guix package: error:   second entry: cairo@1.16.0
/gnu/store/cwqv36m84ipbpwn52wyy560xbxrzknsz-cairo-1.16.0
guix package: error:    ... propagated from pango@1.42.4
guix package: error:    ... propagated from gtk+@3.24.9
hint: Try upgrading both `python-pycairo' and `gtk+', or remove one of them
from
the profile.


I regularly do

guix pull && guix package -u

so I cannot recall how I got into this situation.   I have packages
depending on both gtk+ and
python-pycairo' so it seems I cannot just remove either one of them.  What
would be the best approach to fix this?
