In my up-to-date Testing system, Aptitude suddenly says that many packages are
broken! It also says that many packages are unused and wants to remove them!
Apt-get gives similar errors. I did not do anything recently; I have no idea
what caused this. Kindly help.
$ sudo aptitude install smartmontools
...
0 packages upgraded, 1 newly installed, 117 to remove and 45 not upgraded.

$ sudo aptitude install
