@pitaj Prior to running ./nodebb upgrade I always do apt-get-update apt-get-upgrade so the server is already fully updated.
If there is something else that NodeBB requires then it should be part of the nodebb upgrade command.
I want to show users, categories, tag and groups at the same time on the homepage, is there anyway I can achieve this by using plugin?
I believe there are widgets for each of those!
However, I'd implore you to consider information density- Most users are scared off by even too many categories- putting all that on the landing page will bounce a lot of users!
