HI
from synaptic:

kde-devel:
Depends: kdesdk but it is not going to be installed
Depends: libarts1-dev but it is not going to be installed
Depends: kdelibs4-dev but it is not going to be installed
Depends: kdebase-dev but it is not going to be installed
Depends: libkonq4-dev but it is not going to be installed


My sources.list:
deb http://sg.archive.ubuntu.com/ubuntu gutsy main restricted multiverse universe
deb http://sg.archive.ubuntu.com/ubuntu gutsy-updates main restricted multiverse universe
deb http://sg.archive.ubuntu.com/ubuntu gutsy-security main restricted multiverse universe
deb-src http://sg.archive.ubuntu.com/ubuntu gutsy-security main restricted multiverse universe


Also in sources.list.d I have a list file with the main repository (same as above without the sg. prefix.)


Where can I find those packages? I checked in http://packages.ubuntu.com and it says that kdesk should be in universe...

Also: Is it a good idea to have several mirrors listed in sources.list.d files? Does it allow to find packages missing in not up to date but faster repositories? And also does it allow to speed up downloading of packages by finding the fastest mirror at that time for that package?
