I’d like to use Seafile on my cloud server with Plesk but the extension is not compatible with Cloudlinux OS. Is there a plan to update this extension soon for this OS?
Alternatively, is there any possibility to install it on this operating system without using the Plesk extension?
the Seafile extension for Plesk is not maintained by the Seafile developers, but by the Plesk team. The extension is also very outdated. It uses Seafile 6.2.7.
Provided that cloudlinuxos is a CentOS-based distribution, I would assume that you can install Seafile using the instructions for CentOS: https://download.seafile.com/published/seafile-manual/deploy/using_mysql.md
