Tested distributions⚓︎

• Fedora
• Debian
• Devuan
• LMDE
• Ubuntu
• Mint
• Kali
• Arch
• none others

Problematic distributions⚓︎

• AArch64/ARM64 (host cross-compilation bitness issues)
• Gentoo
• NixOS
• Ubuntu 25.10+26.04 (uutils-coreutils clone)
• WSL/WSL2

All other distributions⚓︎

... are untested and may or may not work. Results strongly depend on your Linux/admin experience.

Detect your distribution⚓︎

If you do not remember which Linux version is installed, check it as follows:

  $ hostnamectl status
    Operating System: Fedora 33 (Thirty Three)
      Kernel: Linux 5.10.15-200.fc33.x86_64
  

• Ubuntu/Debian version:
  

  $ lsb_release -d
  Description:    Ubuntu 14.04.6 LTS
  

• Machine type: i686 for 32-bit x86 and x86_64 for 64-bit x86:
  

  $ uname -m

• uutils-coreutils issue starting with Ubuntu 25.10:
  
  Canonical replaced GNU coreutils (GPL) with uutils coreutils (MIT/Rust/Code of Conduct), which causes several issues, including problems with pseudo-host.
  See Carefully But Purposefully Oxidising Ubuntu and
  Ubuntu 25.10's move to Rust coreutils causes major issues for some executables.
  
  Typical error: couldn't allocate absolute path for 'null'.
  
  In general, uutils-coreutils is currently not recommended for Freetz builds due to immaturity and known issues in multiple tools (date, cp, mv, base64, du, sort, tail, ls, md5sum, dd, sudo, ...).
  
  Workaround: remove uutils-coreutils and install GNU coreutils with
  

  sudo apt-get remove --allow-remove-essential coreutils-from-uutils
