Hi Scott, I believe the problem you're experiencing is linux not allowing you to write to the /usr/local directory structure as it is not owned by your user. I think you have a couple of choices to download the images. The first is to install them into the default directory with sudo, which I wouldn't recommend, the second is installing the packages into a different directory with the -i switch to uhd_images_downloader.py. Perhaps run the following commands
cd ~/ mkdir uhd_images /usr/local/lib/uhd/utils/uhd_images_downloader.py -i ~/uhd_images That should get you the download images I think. Hope this helps, Chris On Tue, Aug 6, 2024 at 4:16 AM Dr. Scott Best via USRP-users <usrp-users@lists.ettus.com> wrote: > > Dear USRP-Users Group, > > > > I installed UHD 4.7 on an Ubuntu MiniPC following the online instructions. > It seems to be working OK, so I tried updating the firmware for an N200 that > I picked up as a test vehicle for my set of new N320s.
