That makes sense. In case you still want to try conky, there might be means  
to make it appear as a dedicated panel that is not overlapped by maximized  
windows, although I did not test that back when I was using Fluxbox (now on  
i3). See e.g.

There is no automatism for this that I am aware of. There are tools like  
`deborphan` and `aptitude search ~o` that may tell you about them. The  
release notes recommend proactively removing obsolete packages:

It's pretty much how I would go about it for a short-term solution. Any  
upgrade/reinstallation of the respective python package may revert your  
change. I would not mind that too much, given that there will not be any  
"unexpected" upgrades to the package while its repositories are not enabled  
in sources.list :)

You're welcome. If anything is unclear/wrong there, feel free to tell me  
directly via e-mail :)
