Title:
  Hashed passwords stored as MD5 hashes in /etc/shadow

Status in system-config-kickstart package in Ubuntu:
  New

Bug description:
  The root password (if specified) and initial user account password
  (required) are encrypted using an (insecure) MD5 hash. The resulting
  kickstart file will build virtual machines that store the MD5 hashed
  password in /etc/shadow for the root and/or initial user.

  Currently Ubuntu uses SHA512 for storing hashed passwords in
  /etc/shadow, but MD5 still works for the sake of backwards
  compatibility. Using MD5 hashes for any passwords is highly insecure
  and should be avoided.

  1) The release of Ubuntu you are using, via 'lsb_release -rd' or
  System -> About Ubuntu

  $ lsb_release -rd
  Description:	Ubuntu 18.10
  Release:	18.10

  2) The version of the package you are using, via 'apt-cache policy
  pkgname' or by checking in Software Center

  $ apt-cache policy system-config-kickstart
  system-config-kickstart:
    Installed: 2.5.20-0ubuntu25
    Candidate: 2.5.20-0ubuntu25
    Version table:
   *** 2.5.20-0ubuntu25 500
          500 http://us.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages
          500 http://us.archive.ubuntu.com/ubuntu bionic/universe i386 Packages
          100 /var/lib/dpkg/status

  
  3) What you expected to happen

  I expected system-config-kickstart to use SHA512 for storing hashed
  passwords. (Hash starts with "$6$".)

  4) What happened instead

  system-config-kickstart used MD5 for storing hashed passwords. (Hash
  starts with "$1$".)
