This is on debian (3.11-0.bpo.2-amd64 #1 SMP Debian 3.11.8-1~bpo70+1 (2013-11-21) x86_64 GNU/Linux).
I was just attempting to "aptitude install ntp". Aptitude told me it would install ntp and libopts25, but would remove 39 other packages that were seemingly random. I cancelled the command with control+c. I ran it again and pressed ? to see what my options were (I am far from proficient with aptitude). I ended up entering "n" to cancel it again. A few minutes later I ran "aptitude install ntp" again and all of a sudden it says 0 packages will be removed. Why did it decide it didn't need to uninstall all those random packages all of a sudden?
