Install UIM robot on Ubuntu 64-bit Linux servers via UNIX/LINUX installation utility (nimldr) may not work and return the below error:

May 27 10:29:27:201 0 nimldr: Could not figure out what operating system you are running!

Another possible symptom is that nimldr is not able to find the hub it tries to attach to.

hubport=parent_hub_port_number (default port for a hub is 48002)

3. Copy the ubuntu Linux installer to /opt on the target system:

4. Copy the nms-robot-vars.cfg answer file (complated on step 2) to /opt.

dpkg -i nimsoft-robot+<OS>_<arch>.deb

6. Execute the script to configure the robot when the installer exits.
