Correct, but gdebi is obsolete, since nowadays apt can install a local
stored package and automatically add dependencies from repos, too.

In the old days apt-get was required to get dependencies provided by
repos and after that dpkg to install the local stored package or instead
gdebi to install a local stored package and automatically resolve
dependencies by repos. Nowadays apt can be used to replace apt-get +
dpkg or to replace  gdebi.

Btw. those using the wget or curl approach should consider to download
signed checksums, too and to verify downloaded packages against the
signed checksums.

I couldn't find an explanation for packages, however it works the same
way as it does for tarballs or ISO files, see

It's probably easier to add a repository, to get this check
automatically.
