I am trying to install Bazzite in a dual-boot setup with Windows, but the installation fails consistently at the following step:
ostree container image deploy
image=ghcr.io/ublue-os/bazzite-deck:stable
exited with code 1
The installer reaches the container image deploy stage and then fails with exit code 1.
I followed the official Bazzite installation guide exactly and also tested both automatic and custom (manual) partitioning, with the same result.
System / Setup
Boot mode: UEFI
Secure Boot: Disabled
Installer: Official Bazzite ISO (re-downloaded and re-written)
Partitioning
Tested both automatic and manual partitioning.
Manual setup:
Existing Windows EFI partition mounted as /boot/efi (not formatted)
New ext4 partition mounted as /
Windows NTFS partitions untouched
The installer accepts the partition layout without errors.
Networking
Wi-Fi connected successfully in the live environment
Network confirmed active before starting installation
USB tethering via phone also tested
The error still occurs
Behavior
The ghcr.io/ublue-os/bazzite-*:stable step runs for several minutes
Disk activity is visible
Installation then fails with:
ostree container image deploy exited with code 1
What I already tried
Automatic partitioning
Manual/custom partitioning
Using existing Windows EFI
Secure Boot disabled
Re-downloading and re-writing the ISO
Wi-Fi and USB tethering
The issue does not appear to be related to partitioning, EFI configuration, or Secure Boot.
The failure happens specifically during the ostree container image deployment phase.
