I want to clean up some stuff and one part is to move my Zammad installation to a new VM. The old installation is running on CentOS7, for the new installation I’ve set up Zammad on Ubuntu 18.04 LTS which is also supported. Both installations are standard installs using the package manager and are at the latest version.
So following the docs, I’ve created a backup using the backup script and restored it also via the script. Unfortunately Zammad is not starting and throws the error:
Jun 27 11:43:31 zammad-websocket-1.service: bundler: failed to load command: script/websocket-server.rb (script/websocket-server.rb) Jun 27 11:43:31 zammad-websocket-1.service: LoadError: library not found for class Digest::SHA1 -- digest/sha1
What is going wrong here? Do I need to manually install some stuff?
Also the restore script reported this error:
bundler: failed to load command: rake (/opt/zammad/vendor/bundle/ruby/2.6.0/bin/rake) LoadError: library not found for class Digest::SHA1 -- digest/sha1
Any idea how to solve the issue?
