Gostaria de fazer um backup diário da minha máquina para outra. O backup é criado via duply, acionando manualmente funciona bem:
$ duply home status
Start duply v1.11.3, time is 2018-11-19 17:07:10.
Using profile '/home/ingo/.duply/home'.
Using installed duplicity version 0.7.11, python 2.7.13, gpg 2.1.18 (Home: /home/ingo/.gnupg), awk 'GNU Awk 4.1.4, API: 1.1 (GNU MPFR 3.1.5, GNU MP 6.1.2)', grep 'grep (GNU grep) 2.27', bash '4.4.12(1)-release (x86_64-pc-linux-gnu)'.
Autoset found secret key of first GPG_KEY entry 'XXXXXXXXXXXX' for signing.
Checking TEMP_DIR '/tmp' is a folder and writable (OK)
Test - Encrypt to 'XXXXXXXXXXXXX' & Sign with 'XXXXXXXXXXXXXX' (OK)
Test - Decrypt (OK)
Test - Compare (OK)
Cleanup - Delete '/tmp/duply.32286.1542643630_*'(OK)

--- Finished state OK at 17:07:40.743 - Runtime 00:00:29.722 ---
No entanto, quando eu coloco o mesmo comando no crontab, isso resulta em um erro:

Bem, claro, então eu criei e instalei uma chave ssh que tem senha na máquina remota - e removi as outras chaves, para que haja apenas uma chance de entrar no archivius (e eu verifiquei duas vezes como de esta resposta e a segunda um lá também . Mas isso não parece ter nenhum efeito sobre esse problema. O que estou perdendo, o que eu negligencio?
Do meu crontab pessoal:
crontab -l
