How to continue Talos 1. Source-based installation

I reloaded ubuntu 16.04.6 (16.04.4 is not available on ubuntu.com). Following TALOS tutorial, went error-free up to TALOS source-based installation, put a copy of talospublic.rosinstall into talospublicws. Tried to run the next rosinstall src command and am getting error in config saying .. Is not a local file, nor a valid URL and unknown url type: talospublic.rosinstall. I do not have permission to just put talos_tutorials.rosinstall (which is sitting in talos public workspace stack) into a ros system directory. I could give myself permission but looking for correct way to proceed. No error logs to look at yet. Thank you for assistance.

could you please not paraphrase error messages? It makes helping you much harder.

Sanatising errors is ok (fi if sensitive information is displayed), but please keep the overall structure and general wording in tact.

Make sure you are inside the talos_public_ws directory, as the first step in the tutorial instructs. If you execute "ls talos_public.rosinstall" you should be able to view the file and have read permissions.

If I may suggest, you may need to get a little bit more familiar with Ubuntu and ROS before attempting to work with humanoid robots, I'm afraid you'll encounter many more situations where things don't work out of the box and at some point not even ROS Answers may be able to help you.

I did everything per instructions in the box. Your advice is appreciated as I often must refer to ROS/Ubuntu notes taken during beginner kinetic/melodic ROS, cad and simulation tutorials. I'll be reloading Ubuntu a few more times before I get everything right.

It would be good if you could show us the exact commands leading up to the error you encountered.

Also show the output of those commands.

If the CWD is supposed to be talos_public_ws, then run a pwd before executing the rosinstall command to verify.

re: reloading Ubuntu: this is not Windows. Everything you're doing should be reversable, and in addition most of what you're doing takes place in your home directory. I'd be surprised if reinstalling everything would actually be necessary.
