Hi, was there been changes in Server Edition Installation? Not using Ubuntu | Manager anymore?
Because I failed to use the upgrade guide (I have always been able to upgrade without problem before), so I need to use the command:
/usr/share/manager-server/ManagerServer -port 88 -path /Manager.io
But the new problem arised, how to make it HTTPS instead of HTTP?
I am using server edition f(Ubuntu 20.04) on a VPS for years and there are no changes in installation nor upgrade since. You need to follow exactly the information at https://www2.manager.io/server/installation/ubuntu/
This also explains how to obtain a SSL/TLS certificate (https)
I am confused because you say you are on Ubuntu but the screenshot you showed is about Windows.
If using Ubuntu make sure your version is compatible. Also make sure that you use Ubuntu server and not Desktop. Then the link I provided, if you follow each code step correctly will install it correctly.
We do not provide installation service. Server edition works as a custom web-server. If you do not have an experience with web-servers, please seek local IT specialist or sign up for cloud edition.
