Hi there -
I tried to upgrade and it didn’t work through the Admin interface, so I tried the ol’ ./launcher rebuild app and that failed too
I get this message right before it fails. This happens after server reboot too. Any tips?
```
An error occurred while installing mini_racer (0.1.3), and Bundler cannot
continue.
Make sure that `gem install mini_racer -v '0.1.3'` succeeds before bundling.
```

Ok turns out it’s a problem with the beta branch of Discourse. I update using the beta branch (not the default of tests-passed). I noticed this recent change to update mini\_racer:
[https://github.com/discourse/discourse/commit/55e33414bbea88d0ba8a3d11fbebccba65e76336](https://github.com/discourse/discourse/commit/55e33414bbea88d0ba8a3d11fbebccba65e76336)
So that tipped me off to switching back over to tests-passed, and it worked for me then. Maybe time to update the beta branch to a new beta version?

I am on stable branch. Now I’m facing this issue

I’m trying to rebuild 1.6.5 after the web-upgrade from 1.6.4 to it failed, and have the same issue:
```

Currently my site is down and I can’t find a way to get it running again.
I tried changing version in the app.yaml file to 1.6.4 as I saw suggested in another post but I see the same issue there. I’ve changed it back to stable for now.
When I did the app rebuild the first time, it pulled a new Docker container image down, so I wonder if that has something in it that’s causing this to break? Is there a way I can roll back to the old container?

Just out of curiosity, I started a fresh Ubuntu 14.04 virtual machine and installed Discourse, following the quick install guide. The only change I made to the app.yml after running the config tool was to choose the stable branch, and when I then bootstrap the container, I get the same errors as in my previous post - so it appears it’s not possible to install a stable series Discourse any longer?
I’m hesitant to move to tests-passed since we have plugins which track the stable series so may not work on the latest and greatest.
Editing launcher line 67 from
```
image=discourse/discourse:1.3.7
```
to
```
image=discourse/discourse:1.3.6
```
allows the container to bootstrap, so I’m going to try that now on my production box. I’m not sure if there is any negative implication with using the older container file, but it does point to the problem being in that area.
**Update**
Changing to container 1.3.6 got my production box back up and running with
```
./launcher rebuild app
```

@falco this is a bit odd, can you have a quick look at this, why is the old bundle lock not installing?

Same issue for me, fails here. `mini_racer_extension.cc:4:24: fatal error: include/v8.h: No such file or directory`.
Did what is says here [bundle install error (fatal error: include/v8.h: No such file or directory) · Issue #37 · rubyjs/mini\_racer · GitHub](https://github.com/discourse/mini_racer/issues/37). Never worked, the error recommended installing 0.1.3 and I just did latest instead and it worked (after uninstalling `libv8` from that issue so not sure if related).
**And doesn’t work with a rebuild after because it wants to do 0.1.3 and fails.**
EDIT: running with the 1.3.6 image… done and working, now to do this with 3 more servers JUST to update mail settings _sigh_

Same issue for me as well. I was on stable, and couldn’t upgrade from 1.6.4 to 1.6.5 because of this issue. Now my forum is down.

OK guys, I’m looking into this right now.

We can back port the mini racer upgrade, it is safe

Ok, the stable branch is working now, just tested in a brand new Digital Ocean droplet.
