bug#63277: python-anaconda-client and conda fail

[Hugo Buddelmeijer]

Sending the patches seems to have worked out just fine. Except that
number 2 got in my own spam folder.

I forgot that I also needed to update python-defusedxml to 0.7.1.

Using guix does feel a bit like a moving target. It is good to learn
how to fix such issues yourself, because they will pop-up often. The
Contributing section [1] of the manual is a good place to start.

Something unrelated: my desktop (gnome) looks sooo much sharper it
seems, so kudos to whoever improved that!

Cheers,
Hugo
