Symptoms
Certain 3rd party plugins may not show up in paper_lantern after installation on cPanel version 100.
Description
On new installations of cPanel version 100, certain 3rd party plugins are not appearing in paper_lantern after plugin installation. This is because Jupiter has become the default theme (paper_lantern has been deprecated). The /scripts/install_plugin script now default to Jupiter:
# /scripts/install_plugin --help
install_plugin /path/to/plugin/archive
Installs features from the specified plugin archive.
Options:
--theme Theme to install the plugin to (default: jupiter).
Workaround
The plugin(s) will need to be installed for paper_lantern. One such example, for the LiteSpeed Web Cache plugin:
/scripts/install_plugin /usr/local/cpanel/base/frontend/paper_lantern/ls_web_cache_manager/ls_web_cache_manager.tar.gz --theme paper_lantern
Another example is the FleetSSL plugin, which has an install.json file that allows the directory option to be used instead of an archive:
/scripts/install_plugin /usr/local/cpanel/base/frontend/paper_lantern/letsencrypt/ --theme paper_lantern
