trouble installing pureftp

hey guys im new to kali and am having problems installing pure ftpd. i run :
"apt-get install pure-ftpd-common pure-ftpd" and this is what it sends back

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package pure-ftpd-common
E: Unable to locate package pure-ftpd

it does the same thing with any other ftp ive tried as well.
not sure what im doing wrong and after searching around it doenst seem like anyone else is having this particular problem. any help would be much appreciated.
also ive seen some people just use ssh and then sftp but i couldnt really figure that out either.

Make sure you have the correct repositories set.
