Looks like errors like 'reference to nonexistent node' will remain until all text will be translated.

Other errors I could not find in the source PO-file. Maybe coordinates are wrong. For example reference 'guix.texi:946' is missing in the https://translationproject.org/PO-files/ru/guix-manual-1.1.0-pre1.ru.po

Thanks for the quick reply!  There’s a few issues left:

Does that make sense to you?

Thanks,
