                                    please show me the env: ```sh sudo su env ```
try again with `dev` ``` acme.sh --upgrade -b dev ```
account.conf is in the CERT_HOME. So, if you use a customized CERT_HOME, please use `--cert-home`

>> But this is not correct. account.conf isn't placed in --cert-home, it is placed in --config-home. Yes, it's `--config-home`. It was just a memory mistake. The wiki is update.
From the larger to the smaller: `--home` > `--config-home` > `--cert-home` acme.sh will find by the order at start up.
