I've had a very similar problem with ssh host tab completion - the primary difference seemed to be that it worked on Mac and not on Linux.  (I never use console these days, so I couldn't tell you about that.)  I solved it as you did - by a more specific call to the completion file(s) in by bashrc.  Although I think I sourced the one specifically for SSH hosts.

I can't remember if it was here (ie. TLUG) or somewhere else that I saw a conversation about the incredibly tortuous routing of Bash startup.  It was months or even a couple years ago.  Essentially, someone had attempted to map out the decision process behind what files got parsed when Bash started depending on all the little check-boxes: is it interactive, is it console, is it login, dozens of others.  The flow chart created was enough to make a hardened system administrator cry.  So the direct route - add what you want to the bashrc - is definitely preferred to trying to actually debug what happened.

Resolved the issue by adding ...

Hello all ... I am currently running Debian Buster and Bash shell. I have a few Host aliases defined in my ~/.ssh/config. Example: Host test-server. So when, in console, I type ...

$ ssh tes

... and hit Tab, then auto-completion fills out ...

$ ssh test-server

When I try to do the same thing in a terminal (urxvt), tab completion does *not* work. The complete host alias has to be entered.

*But* tab completion for ssh host aliases *does* work if entered within tmux running in the terminal.

Any idea how I can get tab completion working for ssh host aliases in the terminal?
