I discovered this same issue a while back on a crunchbang system
http://crunchbang.org/forums/viewtopic.php?id=19722
My bad for not sending it upstream. EuPhobos's patch is better anyway,
because it works for 'admin ', 'sudo ' or 'adm'.
I had forgotten about it until I ran into it again on this debian jessie
box I just installed. That's not surprising, since it's also using
command-not-found version 0.2.38-1. However, it reports itself as an older
version
$ command-not-found --version
0.2.26
That bug is also in
/usr/share/command-not-found/CommandNotFound/CommandNotFound.py
__version__ = "0.2.26"
