Error installing python3-pip for SkywarnPlus

I have installed SkywarnPlus on 1 repeater fine. On a second system, it will NOT install python3-pip correctly. I’ve tried a few fixes, but nothing works. Any help from linux gurus is appreciated.!

Repeaters are running Debian10 ’ Buster '.
Everything installed and working on my repeater fine.
On the club repeater,
python3 installed fine. When I try ’ apt install python3-pip ', I get this:
Reading package lists… Done
