Did you check status of the launcher repo?
`git status`

You should have seen something like this:
```plaintext
# git status
On branch main
Your branch is up to date with 'origin/main'.
nothing to commit, working tree clean
```
so I think somehow your /var/discourse directory is broken - is no longer connected to the repo. Did you somehow tidy up, lose, or rename the .git subfolder?

Sorry, I don’t know. Do you have a .git subdirectory? What is in it?
In my case, the config file looks like this:
```plaintext
# cat .git/config
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "origin"]
url = https://github.com/discourse/discourse_docker.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "main"]
remote = origin
merge = refs/heads/main
```
But this is for reference. I don’t think the fix is to edit a config file!

i have same result
root@amsaal:/var/discourse# cat .git/config
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote “origin”]
url = [GitHub - discourse/discourse\_docker: A Docker image for Discourse · GitHub](https://github.com/discourse/discourse_docker.git)
fetch = +refs/heads/_:refs/remotes/origin/_
[branch “main”]
remote = origin
merge = refs/heads/main
And git status
root@amsaal:/var/discourse# git status
On branch main
Your branch is based on ‘origin/main’, but the upstream is gone.
(use “git branch --unset-upstream” to fixup)

Looks like you must have changed something - your latest `git status` gives you very different results from your previous report. This is mysterious!

For a full reinstall, you need your full backup (including your app.yml file) and a fresh OS on your instance.
The instructions are here: [INSTALL-cloud](https://github.com/discourse/discourse/blob/main/docs/INSTALL-cloud.md)
It might be best to try the install on a new instance. You’ll need to add the new IP address to a temporary subdomain in your DNS. Or, if you are happy with the downtime, just update your DNS to the new IP address.
You do need to have some idea what you’re doing, otherwise you need help. Sorry, I can’t be that help.
