Below is my config.scm: it has 60 lines (if the 61:1 refers to a line???)

after: sudo guix system reconfigure /etc/config.scm

this message:

/etc/config.scm:61:1: schließende Klammer fehlt (in English closing bracket is missing)

I don`t know where is the missing bracket?

Hi! You have to *replace* %desktop-services in your file with the example usage of modify-services from the manual that Gary sent in his previous email.



has to become this:

     (modify-services %desktop-services
       (sane-service-type _ => sane-backends))

Additionally, you have to import the right module that contains the sane-backends package. So you'll have to add "scanner" to your use-package-modules line at the top.
