The Update Manager does not gives any error, it only offers a Partial Upgrade (some fpc packages, and the rest of them are grayed out).
I went along and tried the manual way. So far i installed only fpc with dpkg -i *deb. It complained about:
fp-units-multimedia : Depends: libvorbis-dev but it is not going to be installed
I resolved it by manually installing this packages: liba52-0.7.4-dev libdca-dev libdts-dev libmad0-dev libmodplug-dev libogg-dev libvorbis-dev.
Now i will try to install Lazarus.
Update Lazaus is working, but again:lcl-qt4-0.9.30
libqt4pas-dev : Depends: libqt4pas5 (>= 2.1Qt4.5.3) but it is not going to be installed
Manually:libphonon4 libqt4pas-dev libqt4pas5 libqtwebkit4 libxcb-shape0 libxine1
libxine1-bin libxine1-console libxine1-misc-plugins libxine1-x phonon
phonon-backend-xine
Anyway it's working fine now. Thank you very much. I hope it will be solved in repo too.
