I am running 12.04 server with ubuntu-desktop installed on top. Every so often I get errors on startup and they refer to some package that needs updating.
Sorry Ubuntu 12.04 has experienced an internal error.
You have obsolete packages installed Please upgrade the following packages ...
sudo apt-get update
sudo apt-get upgrade
My question what is happing to cause these packages to become obsolete ( is it just the passage of time and would setting the system clack back a few days make a difference? (i don't think so!)
If it is that somethong has changed, on my system, to cause this error to occur how do (what commands) do I use to examine the "update" events
