After installing GuixSD 1.1.0 into a VirtualBox VM and following the After System Installation steps ( https://guix.gnu.org/manual/en/html_node/After-System-Installation.html#After-System-Installation), the update fails when trying to update nss-certs. Possibly related to #37662 Error: $ guix pull Migrating profile generations to '/var/guix/profiles/per-user/adam'...

I tried this about 4 months previous, and again today, and have been presented with exactly the same error. The error always occurs at 48.3%. A post on Reddit ( https://www.reddit.com/r/GUIX/comments/hxrmzn/guix_system_error/) has the exact same error as this. The error even occurred at the same 48.3%! I selected the Australian Locale (en_AU) during this installation. I am unsure why the locales error is present after installation. I ran the commands it suggested last time and the warning did not disappear, nor did the nss-certs error get resolved. I can run --fallback, but to me this is ignoring an obvious issue with a vanilla system that should work out of the box. Steps to reproduce: * Create new VBox VM * Install GuixSD Graphical * Select Australia locale * Select defaults * boot into the system * $ guix pull * $ sudo guix system reconfigure /etc/config.scm Original post https://superuser.com/questions/1580209/vanilla-guix-1-1-0-reconfigure-fails-on-nss-certs
