Reading Package Lists... Done
Then, I want only download the new packages (if there are any):
host:~/tmp# emidist-upgrade -d
Reading Package Lists... Done
Building Dependency Tree... Done
Calculating Upgrade... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
In this case I don't have any new packages to install, but if they
were any, I will proceed as following:
host:~/tmp# emidist-upgrade -i
Reading Package Lists... Done
Building Dependency Tree... Done
Calculating Upgrade... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Now my system should be up to date.
I now verify if there are some libraries that are became orphan:
host:~/tmp# emidist-upgrade -o
libmedusa0
librsvg1
libsafe
libosp3c102
and I can safely remove them:
host:~/tmp# apt-get remove --purge libmedusa0 librsvg1 libosp3c102
Reading Package Lists... Done
Building Dependency Tree... Done
The following packages will be REMOVED:
libmedusa0* libosp3c102* librsvg1*
0 upgraded, 0 newly installed, 3 to remove and 0 not upgraded.
Need to get 0B of archives.

I didn't remove the libsafe, because this is a special library and there
aren't any packages that depends from it. It's a good idea to install it,
because it helps against some dangerous operations that could be used for
a security attack.
The next step can be to transfer the just downloaded packages in a local
mirror, so that if any other machines need them, it isn't necessary to
download them any more.
This can be done with the -m swith:
host:~/tmp# emidist-upgrade -m
And finally, I can remove all the downloaded packages from the local
repository, because I already have a copy in my local mirror:
host:~/tmp# emidist-upgrade -c
