Hello! Thanks so much for helping me with this.
It looks we've been able to find the following for the config file for dnf:
max_parallel_downloads in /etc/dnf/dnf.conf.
Here's a post on how to increase it - so do the opposite, and set it to 1.
Also, I wanted to ask you about your suggestion for downloading on the phone.
What method or methods were you considering for downloading the packages on a phone? I haven't heard of this before.
Thank you again for taking the time to write back.
I really appreciate it.
