A bug has been introduced in latest i-MSCP LetsEncrypt plugin which prevent new installation of the plugin. This bug will be fixed in next version which will be released in next hours.
The CHANGELOG for next version will be as follow:

- Added: Support for i-MSCP control panel and services SSL certificates
- Fixed: Enforce non-interactive debconf frontend to avoid confusing debug log
