I need to step through the gio command using gdb. For this I need its source code, and symbols. To get these I followed the directions at:

https://wiki.ubuntu.com/Debug%20Symbol%20Packages

duginfod did not work on my Ubuntu 22.04 system. It was therefore necessary to manually down load these. I followed the directions under the heading "Getting -dbgsym.ddeb packages", and then "Automatic Resolution / Installation of necessary packages", on that page. All went well until the find command. This is the command, and the response I got:

Code:

Where did this go wrong? Why does it not seek the right debug package?

I need to step through the gio command because it fails, and in this thread of mine, no one has come up with a solution:
