After upgrading `docker_manager` through the UI (which seemed to go fine), the _Admin_ dashboard just rendered an empty page, even if the rest of the forum seemed to work.
To resolve this, I resorted to run:
```bash
./launcher rebuild app
```
However, during that process, it ran into errors:
```plaintext

```
… and the `error: packfile` just continues to be spammed until interrupted.
From the looks of it, the _git_ repository has become corrupted. But what git repository?
I don’t even have a `/var/www/discourse` folder, so I assume this is inside a container volume?
I am a bit stumped. Thanks for helping!

What do you mean by that?
Normally you’d update `docker_manager` via the _UI_.

Aah! My mistake. I meant UI, not API. I’ll edit it right way.

I tried to have resolved it by starting and entering the app container:
```plaintext
./launcher start app
./launcher enter app
```
Then I verified that the error occurred when calling the git command as the user `discourse`:
```plaintext
cd /var/www/discourse
sudo -H -E -u discourse bash -c 'git fetch --tags --prune-tags --prune --force origin'
```
Resulting in:
```log
error: packfile .git/objects/pack/pack-581fe47ace192793da04d01989a4d1a7f0e6103c.pack does not match index
error: packfile .git/objects/pack/pack-581fe47ace192793da04d01989a4d1a7f0e6103c.pack does not match index
error: packfile .git/objects/pack/pack-581fe47ace192793da04d01989a4d1a7f0e6103c.pack does not match index
etc..
```
I tried to resolve it by renaming discourse and clone a new one:
```plaintext
cd /var/www
mv discourse discourse-old
git clone https://github.com/discourse/discourse.git
chown -R discourse:discourse discourse
```
Once cloned, tried to run the `git fetch` again with no errors!
```plaintext
cd /var/www/discourse
sudo -H -E -u discourse bash -c 'git fetch --tags --prune-tags --prune --force origin'
```
But as I exited the container shell and tried to rebuild again with `./launcher rebuild app`, I got the same error.
Does the `./launcher rebuild app` use a different container than `./launcher enter app` enters?

yes, there are two levels of git, one outside (not including all the cloned plugins!)
your error does indeed appear to occur inside the container … most strange!

Finally got it to work!
I think it was a mixture between a corrupted _git_ and the result of a previous docker upgrade. I resolved it by pruning all docker containers and images:
```plaintext
cd /opt/discourse
./launcher stop app
docker container prune
docker image prune -a
./launcher rebuild app
```
This resulted/ended with:
```plaintext
Upgrade Complete
----------------
Optimizer statistics are not transferred by pg_upgrade.
Once you start the new server, consider running:
/usr/lib/postgresql/15/bin/vacuumdb --all --analyze-in-stages
Running this script will delete the old cluster's data files:
./delete_old_cluster.sh
-------------------------------------------------------------------------------------
UPGRADE OF POSTGRES COMPLETE
Old 13 database is stored at /shared/postgres_data_old
To complete the upgrade, rebuild again using:
./launcher rebuild app
-------------------------------------------------------------------------------------
```
By running the rebuild again, it started working fully:
```plaintext
./launcher rebuild app
```
