I've noticed that the list of installed software that Synaptic
tells me and what I actually can use on my box are not the same. For
example, I can run Evince, but Synaptic tells me that it is not
installed. I have done something to get them out of sync. My guess
is that it happened when I upgraded from Etch to Lenny.
Anyway, is there a way to get Synaptic to "reread" all
installed software? If so, what is it?
I haven't had any luck using the almighty Google this time.
