I tried to install octave-sundials on 16.04



LC_ALL=C sudo apt install octave-sundials

Reading package lists... Done

Building dependency tree       

Reading state information... Done

Some packages could not be installed. This may mean that you have

requested an impossible situation or if you are using the unstable

distribution that some required packages have not yet been created

or been moved out of Incoming.

The following information may help to resolve the situation:


The following packages have unmet dependencies:

 octave-sundials : Depends: octave but it is not going to be installed

E: Unable to correct problems, you have held broken packages.


Perhaps my setting was wrong.


Please give me a clue to kick out the error.

------------------------------------------------

"Perhaps my setting was wrong" - yet again, Octave packaging system is broken. 
It is broken because it wasn't properly spec'ed in the first place.


And this can clearly be seen from the copy-pasted by you messages:

"Building dependency tree" <-> "Some packages could not be installed" - where 
is the EXACT list of packages that could not be installed in the light of 
"Building dependency tree" ?

You and others can provide whatever particular solutions to concrete package 
problems, but Octave packaging system is broken. And no squandering of 
resources on Octave (qt) GUI can hide this fact.

The

"
The following packages have unmet dependencies:

octave-sundials : Depends: octave but it is not going to be installed

"

is a ridiculous error message - obviously any package for Octave depends on it.
