 I attempted to follow the nrfutil offline install instructions. However, I keep receiving the following error when trying to install the device package on the remote pc.

&lt;p&gt;Thank you for your patience. It took me some time to find possible solutions to this issue. &lt;/p&gt;
&lt;p&gt;The core issue is that an upgraded version of nrfutil is needed to use the offline install, but upgrading needs access to the internet. The team is aware about this paradox, and there are two possible workarounds for now: &lt;/p&gt;
&lt;p&gt;1. When installing nrfutil online on a machine with internet access, a .bin is created in .nrfutil/bin/. you can use this binary to install the nrfutil commands offline. &lt;/p&gt;
&lt;p&gt;2. From your error log you can see a reference to NRFUTIL_BOOTSTRAP_TARBALL_PATH. This can be set to the path to a tarball of the nrfutil-core package. I don&amp;#39;t have details on how to create or get this tarball, but I can request some details internally if you want to use this workaround. &lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;I retried the same process again this morning. Also, I am using the Linux version of nrfutil on Ubuntu.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;1. Download nrfutil (linux) to usb stick&lt;/p&gt;
&lt;p&gt;&amp;nbsp; 2. Run&amp;nbsp;./nrfutil prepare-offline ./nrfutil-offline&lt;/p&gt;
&lt;p&gt;&amp;nbsp; 3. nrfutil offline preparation success&lt;/p&gt;
&lt;p&gt;&amp;nbsp; 4. Move usb to offline ubuntu machine&lt;/p&gt;
&lt;p&gt;&amp;nbsp; 5. Mount usb on ubuntu&lt;/p&gt;
&lt;p&gt;&amp;nbsp; 6. run&amp;nbsp;./nrfutil install trace --from-offline ./nrfutil-offline/&lt;/p&gt;
&lt;p&gt;&amp;nbsp; &amp;nbsp;7. Same error as above&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Thanks!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: nrfUtil Offline Install Failing</title><link>https://devzone.nordicsemi.com/thread/533716?ContentTypeID=1</link><pubDate>Fri, 02 May 2025 07:54:50 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:26536f94-894c-4ad6-9d40-e30b5c6388ae</guid><dc:creator>Maria Gilje</dc:creator><description>&lt;p&gt;Hello,&lt;/p&gt;
&lt;p&gt;Have you verified that you are using the correct path to the USB drive? Please include the commands you are using, but feel free to omit any sensitive information. &lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
