KaOS makes regular ISO releases available, so any (new) user is not confronted with a large or complicated first update. Those who already have KaOS installed do not need to reinstall, a regular “sudo pacman -Syu” will always give you the latest.

Known Issues

  • For UEFI installs it is not possible at this time to use any of the three automated partitioning options, only the fourth option can be used
  • If you want to use a GPT partition table on a BIOS system, make sure to set it up following this Guide, the installer’s partitioner can only handle GPT correctly for UEFI
  • If for any reason the install fails, the installer currently does not unmount the partition it needed to use for the install. Before restarting the install either umount manually or restart the Live mode
  • Installing on RAID, LVM, LUKS is currently not possible
  • When a drive contains a LUKS partition, Calamares will not start, see LUKS Bug report. It is needed to remove the LUKS partition before starting the installer

To create reliable Media for booting the Live ISO, please select USB or DVD and follow the instructions for either using an USB flash drive or DVD disc.
