System :: checksum error

I did a hard drive install, and when I try to download libc6, lib6-dev, and the kernel headers, I get checksum errors/download errors all the time. I tried to download these files multiple times and keep getting this error?

I got the same error

The checksum error seems to occur because md5sum tries to validate the file linux-kernel-headers.ds instead of linux-kernel-headers.dsl (and similarly for the others).
While this is not the recommended solution, you can turn off the checksum validation by commenting out line 28 (starting md5sum -c) of /usr/bin/mydsl-wget.
(You should make sure that other packages validate correctly before you try this.)

Please do not defeat the purpose of system integrity checks.
Instead try another mirror. Use control panel to select one.
