Hello and good day,

Parrot OS failed to install as a virtual machine. At the end of the installation process, a popup appears with this text:

Installation Failed

Boost.Python error in job “fstab”.
Command ‘[‘btrfs’, ‘property’, ‘set’, ‘/tmp/calamares-root-1ygnu_nv/swap/swapfile’, ‘compression’, ‘none’]’ returned non-zero exit status 1.

Traceback:

create_swapfile(root_mount_point, root_btrfs)

Any help would be greatly appreciated.

For anyone encountering the same issue: Enabling swap seems to be the issue. Without it the OS installs perfectly fine. Install Parrot OS without swap and make a swapfile afterwards. The Arch wiki has a good section on this: https://wiki.archlinux.org/title/Btrfs#Swap_file The only thing that the Arch wiki gets wrong is the command for creating the swap file. the uuid flag is not recognized by the btrfs command so just remove “–uuid clear” from the command and you’re good to go.
