I built the graphical installer locally. Here's what "guix describe" outputs:
guix be0a613 repository URL: https://git.savannah.gnu.org/git/guix.git branch: master commit: be0a613c10f6c632b58cf19d37a8c1a5987de354 I used the following command in the guix source: time guix system disk-image --file-system-type=ext4 --image -- size=$[16010(281+1)]MB gnu/system/install.scm I specified the size to be as close to the size of my thumb drive as possible without going over. I think I wanted to add my system config to the drive after it has the installer, but later decided against it. I used gnome-disk-utility to put the resulting image on my thumb drive. When I boot from the drive, it goes as expected. I choose my language, country, and time zone. I select to use the graphical installer, choose my keyboard layout, and enter my host name. It then detects my wifi, and I select it. This is when it hangs. A message pops up saying it is connecting to the wifi. I expect it to give me a way to enter the wifi password and other important information, but it doesn't. I left it alone for a good hour with no change. I have not yet tried the officially published graphical installer. I have already put the ISO from the website on the thumb drive so I can see if the wifi selection does not hang when it needs a password. Expect follow-up on this regard later. Thanks! -- -Jesse
