[clug] Upgrading fish

[Bryan Kilgallin (laptop)]

Both my PC and laptop run Ubuntu. The PC has 12.04 LTS Precise. Whereas 
the laptop has 16.04 LTS Xenial.

I have successfully upgraded my favourite command line shell on the PC, 
to version 2.4.0-2.

However, I have not had such success with the laptop, which still has 
fish version 2.2.0.

"fish
friendly interactive shell
Fish is a command-line shell for modern systems, focusing on 
user-friendliness, sensibility and discoverability in interactive use. 
The syntax is simple, but not POSIX compliant."

I like fish's simplicity. But I wonder what significance there might be 
in that non-compliance?

{fish-dbg
debugging symbols for friendly interactive shell
Fish is a command-line shell for modern systems, focusing on 
user-friendliness, sensibility and discoverability in interactive use. 
The syntax is simple, but not POSIX compliant.
This package contains the debugging symbols for fish.}

I don't understand what such debugging symbols are about.
