After 19.04 upgrade: tigercron complains: , --ERROR-- [init001e] Don't have required command DIFF.

[Kevin Dalley]

After my upgrade to 19.04, I started to receive regular tigercron emails:

--ERROR-- [init001e] Don't have required command DIFF.

Perhaps this is a problem with the upgrade process.

This bug was fixed in the package tiger - 1:3.2.4~rc1-2

---------------
tiger (1:3.2.4~rc1-2) unstable; urgency=medium

    Use rmdir to remove the main directory instead of using find.
    (Closes: #931581, #931926)
  * debian/rules:
       - Fix the code creating symlinks (Closes: #909620)
       - Add symlink for 5 and default (Closes: #928641)
  * config: Add the possibility of having a 'default' definition
    and use that one instead of the generic one. This change and

    accounts that are system accounts
  * debian/control: Improve the explanation of the package and reference
    other software for those users that are looking for alternatives.
