Fixing: >>cachyos error: archlinux-keyring signature from christian hesse is unknonw trust<<

I wanted to install cachyos from medium cachyos-kde-linux-240609.iso and on multiple systems and everytime the installer failed with the following error:

cachyos error: archlinux-keyring signature from christian hesse is unknonw trust

How where I able to fix it?

I've opened the terminal and ran the following commands:

sudo pacman-key --refresh-keys sudo pacman-key --populate sudo pacman -S archlinux-keyring

After that, the installation runs through without any issues.

Updateds zfs pool from OpenZFS release 2.2.0 and ZFSBootMenu can not boot from pool, what now?

As mentioned here, ZFSBootMenu prior version 2.2.1 is not able to boot a zpool once updated.

It took me some time and a few tries to understand that the solution is incredible simple.

Based on the official documentation, all you have to do is to:

  • Boot from a live iso like archzfs.iso
  • Mount your EFI-Partition
  • curl -LJO https://get.zfsbootmenu.org/efi
  • cp zfsbootmenu*.EFI /efi/EFI/ZBM/vmlinuz.EFI
  • Umount your EFI-Partition
  • Reboot

I've updated the archzfs iso build script to automatically create a iso file with the latest ZFSBootMenu pre-shipped.

holoiso, black screen after first boot/installation | Intel HD Graphics 5500 and Holoiso, unsupported, sorry

I tried to debug why a fresh holoiso installation is resulting in a black screen on the first reboot.

After spending hours in debugging, a quick answer from the official telegram-chat solved this.

unsupported, sorry

Was the response from the core developer. The Lenovo T450s has a onboard Intel HD Graphics 5500 inside.
