I recently installed the Debian packages produced by running make deb-pkg to compile my own version of the Ubuntu kernel. I had given the kernel the release version 3.19.0-21-secure. All of the packages were installed with that in their names except one: linux-libc-dev. It appears that there is no version information that identifies that packages, meaning that my installation of my locally built linux-libc-dev package probably overwrote the official one.
I am hesitant about removing it because apt-get will remove all the packages that depend on it without asking me. I tried running sudo apt-get install --reinstall linux-libc-dev and I got this error:
Reinstallation of linux-libc-dev is not possible, it cannot be downloaded.
I tried to see if apt-get can locate the official version at all using sudo apt-get download linux-libc-dev and I got:
E: Can't find a source to download version '3.19.0-21-secure-3' of 'linux-libc-dev:amd64'
Aptitude thinks that it's getting the correct package, but it isn't. How can I fix this?
