Installing Debian testing problems with e2fsprogs and signatures couldn´t be verified

As I said yesterday, I am going to share my experiences rebuilding my home infrastructure of linux servers. I used to have RedHat based servers, but since I always have thought tha t bilingualism is a good thing to have ;-) so I am going now for Debian servers.

As some people know, Debian separates different branches of its distribution: stable, testing and unstable. As the names indicate, the level of stability are less in the unstable version. People normally recommends for servers using stable or testing. I go for testing, since sometimes is difficult to get some applications working in the stable branch since they are sometimes quite old.

Anyway, installing Linux could be a bit scaring, but I promise, Debian is not that difficult as It used to be with the new installer. But the last installations that I made, I always went through the same problem:

This installation run will require temporarily removing the essential package e2fsprogs due to a Conflicts/Pre-Depends loop. This is often bad, but if you really want to do it, activate the APT::Force-LoopBreak option.

Internal Error, Could not early remove e2fsprogs

Unlike some sites say, the way of solving this is typing this in other console (using Alt+F2 for instance):

apt-get - o APT::Force-LoopBreak=yes remove e2fsprogs

Then, You can give another try to install the packages that you want to from the menu.

Also if you get a message similar to this one:

The following signatures couldn't be verified because the public key is not available

You need to install the package of the debian keyring to have the signatures of all packages to avoid installing non-verified packages. This could be accomplished typing in:

apt-get install debian-archive-keyring

and issue:

apt-get update

otherwise will not be activated

Of course this is for a minimum installation (for installing any only-console server or router this is enough).

and off We go! enjoy your Debian installation ;)
