W: You may want to run apt-get update to correct these problems
E: Some index files failed to download, they have been ignored, or old ones used instead.
换了清华的源也不行
然后我试图用交大的源下载其他的包 如sudo apt-get -f install build-essential
出现
Reading package lists... Done
Building dependency tree... Done
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
build-essential: Depends: libc6-dev but it is not going to be installed or
libc-dev
Depends: gcc (>= 4:4.0) but it is not going to be installed
Depends: g++ (>= 4:4.0) but it is not going to be installed
Depends: make but it is not going to be installed
Depends: dpkg-dev (>= 1.13.5) but it is not going to be installed
gstreamer0.8-plugins: Depends: gstreamer0.8-visuals (>= 0.8.11) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

还有我装完ubuntu 5.10后有声音 但是不能调大小 按调声音控制探出
Registry is not present or it is corrupted, please update it by running gst-register
