Hello, after reinstalling my Libranet 2.8.1 trial version , I immediately upgraded my adminmenu and then chose upgrade packages using Libranet safe archive. However I tried doing
and this is what happened

root@habo:/home/pablo# apt-get install mozilla-firefox
Reading Package Lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

Since you only requested a single operation it is extremely likely that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
mozilla-firefox: Depends: libatk1.0-0 (>= 1.6.0) but 1.4.1-1 is to be installed
Depends: libgcc1 (>= 1:3.3.3-1) but 1:3.3.3-0pre2 is to be installed
Depends: libglib2.0-0 (>= 2.4.1) but 2.2.3-1 is to be installed
Depends: libgtk2.0-0 (>= 2.4.1) but 2.2.4-3 is to be installed
Depends: libpango1.0-0 (>= 1.4.0) but 1.2.5-2.1 is to be installed
Depends: libstdc++5 (>= 1:3.3.3-1) but 1:3.3.3-0pre2 is to be installed
E: Broken packages

How can I solve this? also i tried installing other applications (vlc, bittorrent) and I still got the same problems... Will apt-get dist-upgrade solve this? I'm kinda scared to use dist-upgrade as I heard that it causes some problems... but I also want to have the latest packages in my system.

apt-get the following packages first:
libgcc1-3.3.3-1
libglib2.4.1-1
and just work your way down the dependencies on the versions
what's happened is although you have the software, an updated version is available, adn thats the version that mozilla was built on

I see I see...So I have to install the needed packages manually? I thought that apt-get will handle the dependencies by itself? Ima try what you said, hope everything goes ok

" I'm kinda scared to use dist-upgrade as I heard that it causes some problems..."

It usually solves problems. upgrade upgrades packages. dist-upgrade upgrades dependancies as well. Sometimes you'll come across the problem you have because you're getting from the "unstable" sources. Debian is often a bit behind simply because they want their binaries to work when released. "unstable" can be just that for days or weeks.

Likely, the dependancies you require are still in "experimental" and aren't stable enough to be put in "unstable". Waiting may be required.

finally I'm back... I kinda screwed my grub by changing the splash image with a bitmap file

Anyway I just performed a dist-upgrade by using libranet's safe archive, I don't know if it is totally the same as apt-get dist-upgrade but it works well for me hehe the last time I did dist-upgrade I had a few errors. Anyway I installed firefox using the testing packages
