ErgenOS 1.1.0

ErgenOS 1.1.0

ErgenOS 1.1 strengthens system recovery, introduces guided post-install Secure Boot support and expands graphical hardware management.

Highlights

• guided Secure Boot configuration through ErgenCTL and ergenos-secureboot
• Microsoft-signed shim with a locally enrolled Machine Owner Key
• signed kernel, GRUB and installed DKMS modules
• snapshot discovery and ErgenCTL rollback through the signed Secure Boot GRUB loader
• ErgenPac Driver Manager with hardware-aware graphics driver recommendations
• reliable automatic GRUB menu refresh for newly created Snapper snapshots
• ErgenCTL 1.1.0.dev-4, ErgenPac 0.2.1 and ErgenOS Welcome 1.0.1
• optional Where Bootloader wallpaper

The complete installation, MOK enrollment, Secure Boot activation, snapshot boot and rollback workflow was validated on a physical Lenovo ThinkPad. The normal system was deliberately made unbootable and successfully restored through an ErgenCTL rollback.

Download and verification

GitHub limits individual release assets to 2 GiB, so the ISO is provided in two numbered parts. Download both parts and SHA256SUMS-1.1.0, then run:

cat ergenos-1.1.0-x86_64.iso.part-* > ergenos-1.1.0-x86_64.iso
sha256sum -c SHA256SUMS-1.1.0

Expected SHA-256:

460c2ab349681cef4922ebba35b180b24f7a17e7182dbf23cc7c99b13b1fdcce

The installation ISO must still be booted with Secure Boot disabled. Secure Boot can be enabled on the installed system by following the setup guide.
