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)? Antony. ---

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](https://docs.ansible.com/ansible/latest/user_guide/vault.html#providing-vault-passwords) For example, export the environment variable ANSIBLE\_VAULT\_PASSWORD\_FILE   \> cat ~/.vault\_pass   my secret vault password   \> export ANSIBLE\_VAULT\_PASSWORD\_FILE=~/.vault\_pass   \> cat vault.yml   test\_var: my decrypted test variable   \> ansible-vault encrypt vault.yml   Encryption successful   \> cat vault.yml   $ANSIBLE\_VAULT;1.1;AES256   31396664626266393563666663383564396130373763666461353063393663306661363237323936   6531356261303835356538386635623232353765393935620a626438303433323139613331303461   38393263613166383935633065613931386330313138346434343234346439643865343062663230   3034316462633364630a353639373438633630376536373964346162353438373832326139633330   33393963383139653930363364393664373638356266663038343961393665636634666433326535   3462326364393361636232306130393138343635396438383661   \> cat playbook.yml   - hosts: localhost     vars\_files:       - vault.yml     tasks:       - debug:           var: test\_var   \> ansible-playbook playbook.yml   ...   ok: [localhost] =\>     test\_var: my decrypted test variable The same decryption shall also work with "--vault-password-file".
