Silverblue 36 can’t apply system-updates(CLI and Gnome-Software). The system reboots, but I get the following message in the Log: “Failed to start ostree-boot-complete.service - OSTree Complete Boot.”.
My solution for this issue on an BIOS-Legacy System( No UEFI) HP HDX-18 Notebook (12 years old):
I reinstalled Fedora Silverblue 36 with the Anaconda customized option ( 1 SSD with Windows 10 BitLocker, 1 HDD with Fedora Silverblue 36) recommended “Fedora 36 btrfs layout”
After the first setup for Gnome i do a “grub2-mkconfig -o /boot/grub2/grub.cfg” because Anaconda have not build a grub-menu and so I can’t start Windows 10.
Reboot and immediately updating the whole System with Gnome-Software and after rebooting again grub-menu was updated correctly.
Now the layering of packages, flat-pack installation etc. works fine without further manual intervention and so Silverblue is now my daily-driver.
I hope this short description helps anybody to solve similar issues.
