I accidentally stumbled upon that I can "apt-get upgrade <package>"
and see what is likely the trigger for held packages. For me, it
always hesitates and waits for approval. Most often, packages I've
seen are being held back because of an upgrade to the next versioning
plateau or because completely brand new packages are being installed
along with.
Being able to "-s" simulate with apt-get is something I always forget
exists. I just test drove it, and it worked for upgrade in general:
apt-get upgrade -s
There wasn't anything held back this time so I can only assume that
simulate would additionally work for:
apt-get upgrade <package> -s
That can be run just like that, as regular User instead of root.
Simulation doesn't give the 100% full picture. It might not generate
enough focus on the held package to answer why it's being held. May be
why I don't remember to use it. I played with simulation a couple
times, and it's a cute trick. At the end of the day, though, I just go
straight for the real upgrade. For me so far, that route has been
informative and has worked safely #1 because it doesn't continue until
I hit the ENTER key again. :)
