@HighDesertBeacon - Jaime,
Please review the link here as to the sequence of steps you take to build an Ubuntu installation error-free for LimeSDR / LimeSDR-Mini:
Look though that thread and start over using this guide - THERE IS a absolute series of steps that you must take to make the installation work properly, so that information is in that link. Follow it for any Ubuntu distro and you’ll be fine. Looks like you will have to install Ubuntu clean again and build with that procedure.
Let us know how it works for you - 73 de Marty, KN0CK
