I've Kali linux 2019-4 latest one I got error of bad archive while selecting mirror but I chose to add mirror later after installation.

# This system was installed using small removable media
# (e.g. netinst, live or single CD). The matching "deb cdrom"
# entries were disabled at the end of the installation process.
# For information about how to configure apt package sources,
# see the sources.list(5) manual.

I added this mirrors which I found on kali linux official documentation but that is not working properly
