Following the advice obtained here, I am trying to get a LetsEncrypt certificate.

These are the instructions:

Step 1:
https://snapcraft.io/docs/installing-snapd

Step 2:
https://certbot.eff.org/lets-encrypt/centosrhel7-apache

My problem is this error message:

# snap install --classic certbot

error: system does not fully support snapd: cannot mount squashfs image using "squashfs": mount:
       /tmp/sanity-squashfs-881328484: failed to setup loop device: No such file or directory

Apparently, RedHat/CentOS are not supporters of snap.

TIA

OS: CentOS 7

Thanks to Leonardo and Michael,

I have made some progress. The snaps application is not supported by RedHat/CentOS. The solution is simple,  just use:

# yum install certbot

The new error message is this:

# certbot certonly --apache

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Could not choose appropriate plugin: The requested apache plugin does not appear to be installed
The requested apache plugin does not appear to be installed

I am trying to find which is the "requested apache plugin". The log mentions "authenticator".

I am hoping that an Apache Certificate will be useful for Dovecot.
