bug#45537: Update fails with this error

[Leo Prikler]

Hi.

This probably belongs to guix-help, but the format is

SUMMARY
[OPTIONAL DESCRIPTION]
CHANGELOG
[OPTIONAL SIGNED-OFF-BY]

each separated by two line feeds.  Very importantly, the summary should
contain the name of the package being changed (if one is changed at all
– there are also commits affecting build systems etc.), and so should
the changelog.  You can therefore pretty easily grep the logs for the
last commit, in which a variable was introduced, removed, changed,
moved, etc.
For instance, searching r-snpstats in the web interface quickly yields
the commit I've posted earlier as the one in which the bug was fixed.

Regards,
Leo
