I would not recommend using dict in this matter, a easier solution is to use
include_vars
https://docs.ansible.com/ansible/latest/modules/include_vars_module.html
If you still wanna use dist it will look something like this
{{ ospackages | dict2items | selectattr('value.state', 'eq', 'present') |
list | map(attribute='value.Ubuntu.1804') | list }}
