Obvious question, but have you checked whether any other process happens to be
running apt at the same time (eg: a cron job checking for available updates)?

Never use sed when tr can do the job.

Avoid using cat whenever possible.

I think its something to do with the become method

when i do it like this it works

using command 

ansible-playbook httpd.yml --ask-vault-pass

I want to skip the password prompt but when i use 

fails

how do I not have to enter my vault password?

--
- hosts: all
  become: yes
  vars_files:
    - ~/ansible/vault.yml      
 
  vars:
    ansible_become_pass: '{{my_become_pass}}'

  tasks:
   - name: Installs nginx web server
     apt:
      name: apache2
      state: present
      update_cache: true

  handlers:
   - name: start httpd
     service:
      name: httpd
      state: present

I can only get this playbook to work with

ansible-playbook httpd.yml --ask-vault-pass

and entering my vault password

When I run the playbook with

-vault-password-file

I get

[WARNING]: Error in vault password file loading (default): A vault password must be specified to decrypt data
ERROR! A vault password must be specified to decrypt data

"--vault-password-file" should work. Is it the leading double dash missing
which causes the problem?

See "Providing Vault Passwords"
https://docs.ansible.com/ansible/latest/user_guide/vault.html#providing-vault-passwords

For example, export the environment variable ANSIBLE_VAULT_PASSWORD_FILE

shell> cat ~/.vault_pass
my secret vault password
shell> export ANSIBLE_VAULT_PASSWORD_FILE=~/.vault_pass

shell> cat vault.yml
test_var: my decrypted test variable
shell> ansible-vault encrypt vault.yml
Encryption successful
shell> cat vault.yml
$ANSIBLE_VAULT;1.1;AES256

3462326364393361636232306130393138343635396438383661

shell> cat playbook.yml
- hosts: localhost
vars_files:
- vault.yml
tasks:
- debug:
var: test_var
shell> ansible-playbook playbook.yml
...
ok: [localhost] =>
test_var: my decrypted test variable

The same decryption shall also work with "--vault-password-file". Let's unset
the environment variable first

shell> unset ANSIBLE_VAULT_PASSWORD_FILE
shell> set | grep ANSIBLE
shell> ansible-playbook playbook.yml --vault-password-file ~/.vault_pass
...
ok: [localhost] =>
test_var: my decrypted test variable

Last option is to configure the path to the file with the vault password in
the configuration file. See "vault_password_file"
https://docs.ansible.com/ansible/latest/reference_appendices/config.html#default-vault-password-file

HTH,
