trying to figure out the correct way to upgrade, installation was done using the install script on a base install of debian 12 as recommended, now i want to know how to upgrade it and there doesnt appear to be a clear way to do this ?

ive tried running the install script again but keep getting this error:

```bash

```

docker pull images is suggested but no details on how to do this, im very familiar with linux just not with how anthias is setup using docker/ansible/python etc

any help is appreciated

Try running the installer again. That should sort the issue out.

ive already done that, hence the error i posted above.

i just tried:

```auto
systemctl stop anthias-host-agent docker
cd /home/signage
rm -rf anthias* installer_venv/ screenly* version.md .ansible/ .anthias/ .screenly
bash <(curl -sL https://install-anthias.srly.io)

```

and still get the same error, yes i could just blow the install away and start fresh but i want to understand whats going wrong, i should be able to update an existing install surely ?

EDIT: found this on github which fixed the issue:

EDIT2: no it didnt fix it at all i had to:

```auto
docker rm -f $(docker ps -aq)
docker rmi -f $(docker images -q)
cd /home/signage/anthias
docker compose up -d

```

now i have the latest images as the interface is completely different, after running the previous script i still had docker images that were 6 weeks old, all good at least i know how it works now

EDIT3: nope its still broken, after reboot i get a black screen, the web interface works but nothing on screen except an underscore in the top left…

Could you try upgrading to Trixie? Things _should_ in theory work on Bookworm, but the matrix of supported devices/debian versions is getting very big and hard to test.

upgraded to trixie, ran your fixed installer, still didnt work, removed all traces of anthias from the system including docker images/containers, ran the fixed installer script again which worked but now i get this constantly in the journal and i cant shutdown the system from the web interface

```auto

That is strange indeed. How did you invoke the installer?

Try running it like this:

`bash <(curl -sL https://install-anthias.srly.io)`
