Dependency/conflict resolution - introduction.
One or more of your choices have raised a conflict or dependency problem -
some packages should only be installed in conjunction with certain others, and
some combinations of packages may not be installed together.
You will see a sub-list containing the packages involved. The bottom half of
the display shows relevant conflicts and dependencies; use 'i' to cycle between
that, the package descriptions and the internal control information.
A set of 'suggested' packages has been calculated, and the initial markings in
this sub-list have been set to match those, so you can just hit Return to
accept the suggestions if you wish. You may abort the change(s) which caused
the problem(s), and go back to the main list, by pressing capital 'X'.
You can also move around the list and change the markings so that they are more
like what you want, and you can 'reject' my suggestions by using the capital
'D' or 'R' keys (see the keybindings help screen). You can use capital 'Q' to
force to accept the situation currently displayed, in case you want to
override a recommendation or think that the program is mistaken.
Press <space> to leave help and enter the sub-list; remember: press '?' for help.
