How to add a variable with a list of services into another list of services?
Hi, I'm trying to write a module with this list of services: (define bar (list (service foo1-service-type) (service foo2-service-type))) How do I add the "bar" variable into the "(services..." declaration which already contains a list of services? I've tried without success: (services (append (list ...) bar (modify-services %base-services... Thanks in advance!

Re: scanning in GNU Guix
Hi Lukas, thanks very much for looking into that. Please inform me, when we are going to get there. It is always a nuisance, when I need a scan, I have to start GNUinOS, which I have installed approx. 2 years ago, scan something and then to restart my laptop with Guix to continue working. I tried to install Trisquel in a VM, but I am not able to change the Samba configuration so that it works that I can scann in Trisquel and save the scan in my Guix home folder. At the moment there is only one solution not to restart my laptop: to scan in Trisquel in adding my printer and a usb device, save my scan on the usb device, after scanning remove my printer and the usb device so that I can use the usb device in Guix and start Trisquel next time. If I don´t remove my printer and the usb device every time after using it, I can´t start Trisquel in the VM. Then I need to have the printer and the usb device connected to my laptop which is not a good option. I am wondering why it works that way.

Am I guessing correctly that your printer is connected through the network, not USB? My printer is connected with USB to my laptop. Is than all you have written valid for me also? The USB case is probably different. For testing, I connected my printer via USB and experimented a bit with it. With `lsusb' I can see the printer, but the hp-setup utility can not find the printer at all, even if I put the Bus and Device number into hp-setup manually. My guess is there is a problem with the USB support in our hplip package. My understanding (but i may be wrong) is that the HP drivers from the hplip package are needed to be able to both print and scan - to only get printing to work, a generic driver may suffice. I'll try to look into the USB support of our hplip package, if/when there is time. I agree with you that printing and scanning should just work - we are not there yet but we will get there eventually 🙂 Best, Lukas OpenPGP_0xD9E413C6C4BB32CE.asc Description: OpenPGP public key OpenPGP_signature.asc Description: OpenPGP digital signature

Hello Gottfried, gfp writes: > I can print in Guix SD with my very old printer > HP Officejet J4580 All-in-One > but I can´t _scan_. I had the same issue with my HP printer. Am I guessing correctly that your printer is connected through the network, not USB? Until very recently, our hplip package (containing the printer drivers for HP devices) did not have network support. This means that you could not use the HP drivers with a network connected printer. The reason you can print in spite of that is that you are likely using IPP to communicate with the printer (at least this was the case for me). This does however not support scanning. To scan and print, you need to use the HP drivers. A fix to enable the network support of hplip was merged two days ago (bug#76583). So if you pull and then reconfigure your system, both scanning and printing should work. Make sure that your CUPS service is actually using hplip instead of hplip-minimal (the latter does not have network support). In my system configuration file, I do this: (service cups-service-type (cups-configuration (web-interface? #t) (auto-purge-jobs? #t) (default-paper-size "A4") (extensions (list cups-filters epson-inkjet-printer-escpr hplip;; <- hplip, not hplip-minimal You will likely also need to add the printer to CUPS again, because you want to use the HP driver, not IPP. You can do that conveniently using the hp-setup utility that comes with hplip. Run it with guix shell hplip -- hp-setup and select "Network/Ethernet/Wireless network ..." (in the bottom left of the window it should say "Step 1 of 3"). If you click on "Next" it will try to find your printer automatically. If this does not work, go back to Step 1 of 3. Under "Show Advanced Options" you can enter the IP address of your printer manually. Once hp-setup has successfully configured your printer, you should be able to print and scan (the scanner should be found automatically by e.g. Simple-Scan). > So, what is the difference between > GNU Guix and GNU Trisquel > that I can´t scan in GNU Guix? I believe the difference is only the network support in the hplip package. With this now fixed, the functionality should be equivalent. Hope this helps! Best, Lukas
