That is, it works but it takes an unreasonably long time to do so. How
can it be that, DNF knows the package is already installed and /still/
takes such a long time to decide that dependencies are ok? There aren't
any dependencies to resolve!
I can't replicate this:
$ time sudo dnf install firefox

I've seen this. If this is an upgraded machine (I mean like from
F21->F22->F23 or something), then rpm (and hence dnf) actually takes a
while to plow through all the entries in its database to make sure
everything's up to snuff. If it's a fairly new machine (very few
upgrades) then it's fast.
My machine at home has been upgraded (with MANY a fight!) from F18 up
through F23, so rpm takes a LONG time. For example, try something like
rpm -qa | grep ssh
Time that on a new, fresh install and on one that's been upgraded
several times. You'll see what I mean. I've tried to purge rpm's
database to speed it up:
rm -f /var/lib/rpm/__db*
rpm --rebuilddb"
but it's never seemed to help. I guess there's enough crumbs left in
the various /var/lib/rpm directories for it to pretty much put
everything back in there and frankly, it doesn't bother me that much.
