Since the README was inside the .tar, there was no info about what to do.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/337279?ContentTypeID=1Wed, 03 Nov 2021 13:26:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e0690b42-5e0e-4e81-b804-248cca9e2c8dwlgrd<p>You also need to do&nbsp;</p> <p>`tar -xvf nrf-command-line-tools-10.15.0_Linux-amd64.tar.gz`</p> <p>then `<span>sudo dpkg -i&nbsp;JLink_Linux_V756a_x86_64.deb`&nbsp;&nbsp;</span></p><div style="clear:both;"></div>
