To update both, run the following commands:
- ⚠️ Important: The commands below create, copy, edit, or move files in the root directory; see XFS Features and Root Immutability in Nitrux.

sudo overlayroot-chroot

mount -t devtmpfs /dev dev

pipx uninstall --global nx-apphub-cli

pipx uninstall --global nx-apphubd

pipx install --global git+https://github.com/Nitrux/nx-apphub.git

pipx install --global git+https://github.com/Nitrux/nx-apphubd.git

umount /dev

sync

exit

Now run the command touch $HOME/.config/nx-apphub/aliases.zsh and Reboot to load the changes into the overlay.

📌 PSA 13/11/25

PSA: We’ve updated the ISO files due to an issue caused by Casper that prevented the Live user password from working in software using PolicyKit, due to a Casper initramfs hook script that blanked the password. The problem didn’t affect user accounts in installed systems, only the Live user.
- The new ISO files are:
  - nitrux-contemporary-cachy-nvopen-0495596d-amd64.iso
  - nitrux-contemporary-liquorix-mesa-97d71fec-amd64.iso
