Note that I do most of my buiding with --no-grafts.

Not sure they are related:

The two errors are not related. When I choose a different target
profile the second error goes away. 

In a clean profile both errors will probably go away...

This is due to an ABI change a few weeks ago.  Just run “make clean-go

I can’t seem to reproduce it:

Could you check if the problem occurs with current Guix, and if it does,
whether the above command is easy to reproduce it?

Thanks for reporting it!

Depends on the machine and what it is used for. Yes, for services that
can be vulnerable you need to use grafts using an older guix tree. But
I mostly build against git checkouts of guix - which means I am using
the latest versions of packages anyway. Agree?

clean-go is a new one for me.

I am using current Guix. The problem occurs on an existing profile. On
a new profile it does not happen.

I remember the python.1 path is a symlink not pointing anywhere. We
dealt with that a year ago. Maybe it now confuses the man db builder.
Does it somehow use the (existing) profile?

Note that python-2.7.3 is the newly installed package.

Yes, sure; I just wanted to make sure you had check the “I understand
the risks” box.  ;-)

Yes, it could be that it happens with a particular combination of
packages in the profile.

Could you try to see if you could reproduce the problem in a fresh
profile starting from what the offending profile has and gradually
reducing the package set?

Thanks,
Ludo’.

I can reproduce the problem, but I can not reproduce the environment.
I tried.

All I can see is that when the profile gets updated the new path

  $profile/share/man/man1/python.1

is a symlink pointing to nothing. You can see that when installing
python-2.7.13.

All I can tell is that the version that was installed (2.7.11).
actually pointed to something. When overwriting the old version,
strangely, the man pages generator balks.

Strangely because installing in a fresh profile gives no complaints.

The old package path was

  /gnu/store/vcx1n5nj4gr52xx5m6gvi7zrwngy06s3-python-2.7.11/share/man/man1/python.1
