E: The package libc6 needs to be reinstalled, but I can't find an archive for it.

Whatever I set, it produces this line. I don't know how to install this libc6 package.
And in general, what should I read the information in order to understand what apt-get is so that there are no problems installing software on Linux. Thank you.
