Trying to upgrade discourse to latest version, but before that I need to upgrade docker manager and
getting following exception while upgrading:

Are you 100% sure you are not running any plugins except for docker\_manager?

You are probably better off letting it upgrade all of them by logging into the server and running
```plaintext
./launcher rebuild app
```
Especially if you are following tests-pased, as a lot of those plugins have had changes due to recent Core changes.

The problem here is the ruby 2.3 syntax - @tgxworld told it was safe to use, but perhaps it is not?

The guy isn’t running the latest docker image, the latest enforce ruby 2.3.

Yeah and I’m getting this exception while upgrading docker\_manager.

Doesn’t a simple:
```plaintext
cd/ var/discourse
git pull
./launcher rebuild app
```
works?
The docker manager isn’t used to update the launcher, and is need on the big transition upgrade (ruby, pg, nginx, etc update from earlier this month).

That was my questioning too. In theory, I would think that would solve his issue.

Hmmm this is odd. I added a check to make docker manager raise an error and make the user rebuild if Ruby is not 2.3. Will have a look next week.

Hmm I can’t find a `<<~JS` ` heredoc anywhere (including your plugins).
Have you resolved the issue?
Otherwise, can you run the following commands and provide the output here?
```plaintext
./launcher enter app
ruby -v
cat /VERSION
```

Ah I found it but the syntax we’re using is different and I’m not sure how to reproduce yet.

Did the trick. Thanks 🙂
