Hello, sorry because I forgot to give details, I would like to install HTTPS mode of Redmine on Ubuntu 18 or 20 (I have both). Note : I already succeed to install Redmine bitnami. I also would like to install several instances of bitnami on a same server.

I thank you for your reply.

Thank you to advise me. I installed bitnami Redmine.

I am wondering if there is a guide to install HTTPS on Windows ? Or it is in the first link you gave me (Windows binary for Lego) ? Please
