Yes Oli, that's what I wanted to point out. Mentioning that the OP made
a typo and mentioning that the OP should consider to copy and paste
commands might have been better, than my short reply. maybe I also
should have explained how to use a terminal's auto-completion.

The OP seems to use a GUI, I suspect "Ubuntu software installer" is for
"Ubuntu Software Center". Too funny is this post, because it's related
to the same issue, that virtualbox from the Oracle download site can't
be installed using Ubuntu Software Center:

http://askubuntu.com/questions/110059/why-wont-ubuntu-software-center-install-deb-files

But as already pointed out, it's even possible to install without
gdebi.

We should assume that the packages apt and dpkg are installed on every
default or customized Ubuntu install.

Let alone that a web search such as

  install a local package with ubuntu software center

provides the above link as the first hit when using startpage.com. For

  install a local package with ubuntu software installer

it's the third hit, among several other useful links.

Here is something interesting, if I type d and then the tab-key, there
are to many commands, so I replied "n"o.

If I type dp and then press the tab-key I get a list with dpkg related
commands and dput.

If I type dpk and then push the tab-key, I get dpkg:

[root at moonstudio ~]# d
Display all 253 possibilities? (y or n)
[root at moonstudio ~]# dp
dpkg                     dpkg-divert
dpkg-parsechangelog      dpkg-split dpkg-architecture
dpkg-genbuilddeps        dpkg-preconfigure        dpkg-statoverride
dpkg-buildflags          dpkg-genchanges
dpkg-query               dpkg-trigger dpkg-buildpackage
dpkg-gencontrol          dpkg-reconfigure         dpkg-vendor
dpkg-checkbuilddeps      dpkg-gensymbols
dpkg-scanpackages        dput dpkg-deb
dpkg-maintscript-helper  dpkg-scansources dpkg-depcheck
dpkg-mergechangelogs     dpkg-shlibdeps dpkg-distaddfile
dpkg-name                dpkg-source
[root at moonstudio ~]# dpkg

Now the bomb drops, if I type dk and after that hit the tab-key I get
nothing.

[root at moonstudio ~]# dk
