The error I see is
```plaintext
awk: fatal: cannot open file '/root/.ssh/authorized_keys'
```
Here’s the full output:
The site seems to still work. Anything to worry about? Should I do something?

If I remember correctly that is a relic of an old template we used to had, in the days before `docker exec -it bash` was a thing.
It’s safe to ignore, but you can also remove the related lines from your app.yml if it bothers you.

If you share your app.yml here we may be able to tell exactly which ones.

comment or remove this template and try rebuilding again. this is most probably the culprit.
EDIT:
The error is originating from this line:
> [@trusktr](#):
>
> ` - exec: awk -F\# '{print $1;}' ~/.ssh/authorized_keys | awk 'BEGIN { print "Authorized SSH keys for this container:"; } NF>=2 {print $NF;}'`
You can comment the following line and try again, the error should then disappear

Thank you! Looks like I inherited that from the previous person that ran the instance. Sorry for wasting your time on this issue that turns out not related to Discourse.
