For those running a Linux OS, some important details:
It is mentioned in the Download section on the Arpado site which Linux versions are currently supported. Due to the many different distros and Linux versions, our development efforts are being put on supporting out of the box those that are most famous:
Ubuntu 16 and up (Tested, Running)
Mint Sarah and up (Being Tested)
Cent OS (In Progress)
We cannot go through each one of these distros and versions, so we must stick to a base version in order to support newer ones. Arpado uses low level libraries that change almost on every new Linux release, hence the requirements are specific. However, there may be workarounds that will enable Arpado to work in your system.
If you have any issues, post your message here mentioning all the details (OS, distro, version, CPU/RAM architecture, etc) and we'll happily assist you.
