2 newbe queries

[dave]

Hi all,

Thanks for the sources lists, they were a great help :) .... a couple of newbe 
points though.

I installed abiword (not in ubuntu official) all OK, I installed eric3 (not in 
ubuntu official) and it would not work, an error in its python code, I guess 
its still being worked on in Debian testing.

If I have a working package ie abiword, and I upgrade it at a later date from 
debian testing the updated abiword may be broken. If so is there a way of 
reverting to the old working abiword ?

Also there appears to be ...

(1) Official packages ... the core od ubuntu, I understand that

(2) Community supported packages ... what are these ? What is the difference 
between these & (3)

(3) Packages not included in ubuntu ... I guess thats the great ocean of 
packages that is Debian testing

Thanks for your indulgence :)

Dave
