Using Ubuntu Server 20.04.xx LTS is highly recommended for running Flux Nodes due to its stability and compatibility. The acronym LTS stands for "Long Term Support" which signifies that Ubuntu will provide updates and patches for this operating system until 2030.
Other supported operating systems include Ubuntu versions 16, 18, 19, 22*, as well as Debian 9 and 10. 
For home hosted servers we recommend that you open port 22 on your router. This will allow you to connect your router remotely and carry out any maintenance without having physical access to the hardware.
*Ubuntu 22 is supported only if your CPU supports the AVX instruction set. You can determine whether your CPU is supported by running the following command in your Linux terminal:
cat /proc/cpuinfo | grep -o avx | head -n1
If the command returns "avx" or similar then you can proceed with the installation of Ubuntu 22. However, if it returns no value (a blank line), it means that your CPU is not compatible, and you should stick with Ubuntu 20.
