Issue Details

I am trying to install third-party Linux software in myRIO using OPKG Package Manager via SSH connection, but execution of "opkg update" command results in wget bad address error: 
admin@NI-myRIO-1900-0304756e:~# opkg update

Solution

In order to solve that problem execute the following command from a SSH logged in as "admin": 
sed -i 's#nickdanger\.amer\.corp\.natinst\.com/feeds/\([^/]\+\)/\([^/]\+\)/#download.ni.com/ni-linux-rt/feeds/\1/\2/ipk/#' /etc/opkg/base-feeds.conf
This will need to be run each time you format your target, possibly after software installation through NI Measurement and Automation Explorer (MAX) as well.
 

Additional Information

The OS image that ships with LV 2017 and RIO 17.0 has the opkg feeds configured to point to the internal-to-NI feed server and therefore you will be unable to install software through OPKG without changing the configuration in a configuration file.
