Hi, I ran into the same symptom - aptitude stuck at "Loading cache" after `aptitude -u` - after I had added the line deb http://snapshot.debian.org/archive/debian/20160924/ sid main non-free contrib into sources.list. What revealed the root cause in my case was running `apt-get update`, which produced the error message: E: Release file for http://snapshot.debian.org/archive/debian/20160924/dists/sid/InRelease is expired (invalid since 1d 21h 41min 22s). Updates for this repository will not be applied. This is known behavior and running aptitude as `aptitude -o Acquire::Check-Valid-Until=false -u` suppresses the error and aptitude works as normal. What seems to be common between your setup and mine is that an error during the update of the package lists isn't handled (anymore; this worked previously) and that causes trouble later.
