I cann't install libqt3-dev on my woody3.0 KDE 3.0.3 because agt-get says: 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: Sorry, but the following packages have unmet dependencies: libqt3-dev: Depends: libmng-dev but it is not going to be installed Depends: libpng-dev (>= 1.2.1-1) Depends: libjpeg62-dev but it is not going to be installed or libjpeg-dev Depends: zlib1g-dev but it is not going to be installed or libz-dev E: Sorry, broken packages What can I do?
