[讨论]apt-get问题，为什么老是unable to locate pakage 呢？是源的问题吗？ [复制链接]

我尝试用apt-get装xlibs-dev的时候出现E:unable to locate pakage xlibs-dev  我已经添加了别的源网络也没问题，请问是怎么回事呢？
升级源的时候出现以下错误：

root@ubuntu:/home/uptech/QT4/for_x11/qt-x11-opensource-src-4.4.0# sudo apt-get install xlibs-dev
Reading package lists... Done
Building dependency tree      
Reading state information... Done
xlibs-dev is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
xlibs-dev : Depends: libice-dev but it is not going to be installed
             Depends: libsm-dev but it is not going to be installed
             Depends: libx11-dev but it is not going to be installed
             Depends: libxext-dev but it is not going to be installed
             Depends: libxi-dev but it is not going to be installed
             Depends: libxmu-dev but it is not going to be installed
             Depends: libxmuu-dev but it is not going to be installed
             Depends: libxpm-dev but it is not going to be installed
             Depends: libxrandr-dev but it is not going to be installed
             Depends: libxt-dev but it is not going to be installed
             Depends: libxtrap-dev but it is not installable
             Depends: libxtst-dev but it is not going to be installed
             Depends: libxv-dev but it is not going to be installed
             Depends: x-dev but it is not installable
             Depends: zlib1g-dev but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

注意标题啊，这样的标题词只会引人反感啊。
