md5deep ubuntu install - command not found

Question

I am trying to use md5deep on ubunutu. I have run the following commands:

sudo apt-get update
sudo apt-get install md5deep

This successfully installs. However, I then run:

md5deep

And get the error message:

 md5deep:command not found

I have read the first 10-20 google pages on installing this and watched a number of youtube videos but unable to get part this first step.

Can anyone explain what I am doing wrong here? (not sure if this is a linux question rather than a md5deep question)

My output for:

dpkg -L md5deep

is:

/usr/share/doc/md5deep
/usr/share/doc/md5deep/copyright

TLDR: This is bug of hashdeep package (since debian); Use hashdeep -c md5 in older ubuntu; fixed in 17.04 (upgrade your ubuntu or try to downgrade package or use backports; or try to recompile into deb newer package or do sudo ln -s /usr/bin/hashdeep /usr/bin/md5deep or sudo ln -s hashdeep /usr/bin/md5deep as hack).

In debian and Ubuntu (some version before 16.04 or in it, actually 15.10) md5deep package was replaced by hashdeep package. Now, in 17.04 "zesty" md5deep is not a real package but just a "link" (transitional dummy package) to hashdeep package:

http://packages.ubuntu.com/zesty/md5deep

transitional dummy package for hashdeep

Most recent version of hashdeep (from 17.04 "zesty") http://packages.ubuntu.com/zesty/hashdeep can be installed by sudo apt-get install hashdeep and has all needed commands:

http://packages.ubuntu.com/zesty/amd64/hashdeep/filelist (only /usr/bin part)

/usr/bin/hashdeep
/usr/bin/md5deep
/usr/bin/sha1deep
/usr/bin/sha256deep
/usr/bin/tigerdeep
/usr/bin/whirlpooldeep

But the problem (bug) is that 16.04 and 16.10 versions of hashdeep lacked 5 additional names in /usr/bin including md5deep:

http://packages.ubuntu.com/xenial/amd64/hashdeep/filelist http://packages.ubuntu.com/yakkety/amd64/hashdeep/filelist

 /usr/bin/hashdeep
