Can't delete users from the CLI


  • Used Zammad version: 3.3.x
  • Used Zammad installation source: (source, package, …) package
  • Operating system: 4.15.0-88-generic #88-Ubuntu SMP Tue Feb 11 20:11:34 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux


I get an error when I try to delete a user:

zammad run rails c

Loading production environment (Rails
irb(main):001:0> User.find(60)

Any ideas?

Most users can be deleted if I remove the them from the customer group, but not all.

Do yourself a favor and use our official provided scripts - they will safe head ache.
