can not install alien, rpm, nsis in kali

[craigliu]

When I check my openvas, I have this warning:
WARNING: Could not find rpm binary, LSC credential package generation for RPM and DEB based targets will not work.
SUGGEST: Install rpm.
WARNING: Could not find makensis binary, LSC credential package generation for Microsoft Windows targets will not work.
SUGGEST: Install nsis.

Then I install them by:
# apt-get -y install alien rpm nsis
...
E: Unable to locate package alien
E: Package 'rpm' has no installation candidate
E: Unable to locate package nsis

How can I install alien, rpm and nsis? My sources.list has only repositories of kali and kali-security.

Thanks for help.

Any solutions for this?

apt-get -y install alien rpm nsis fakeroot
