Hello.
I uploaded a new PO-file.
Hope it fixes that error.

Hello Pavlo,


Thanks for the update to the Russian translation of the Guix manual!  It
contains a couple of Texinfo syntax errors:

--8<---------------cut here---------------start------------->8---

Could you take a look and post an update on the Translation Project?

Let me know if you need help to address these.
