（已解决）无法运行sudo apt-get install build-essential

无法运行，如何解决，更换了好几个源，还是一样

lenovo@lenovo-desktop:~$ sudo apt-get install build-essential

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:

The following packages have unmet dependencies:
build-essential: Depends: libc6-dev but it is not going to be installed or
libc-dev
Depends: g++ (>= 4:4.0) but it is not going to be installed
E: Broken packages

换源后解决
