Hi everyone and thank you for great forum!
While trying to install akismet, running:
`sudo ./launcher rebuild app`
gives me such error:
```
Ensuring launcher is up to date
Fetching origin
Launcher is up-to-date
(): found a tab character that violate intendation while scanning a plain scalar at line 91 column 13 -e LANG=en_US.UTF-8
YAML syntax error. Please check your containers/*.yml config files.
```
in my /containers/app.yml I have:
```
## Which Git revision should this container use? (default: tests-passed)
#version: tests-passed
env:
LANG: en_US.UTF-8
# DISCOURSE_DEFAULT_LOCALE: en
```
Please help me to solve this issue

You have a tab in your yml file and that’s a problem.
The surest solution is to delete your yml file and run discourse-setup again. Or you can find the tab and replace it with spaces.

There’s something wrong with your docker installation, how was docker installed?
What’s the result of doing:
`docker info`
The last time I saw this error the user had installed docker both from get.docker and separately via apt.

Did you install it using snap? That isn’t supported.

We don’t support that installation method here, the only supported install is the [official install method](https://github.com/discourse/discourse/blob/master/docs/INSTALL-cloud.md).
Your `docker info` confirms that docker was installed using snap. Your options are to either ask DigitalOcean for support as you’ve followed their method, or use the [official install](https://meta.discourse.org/t/142537?silent=true) method linked above.

Oh, sure I will reinstall it, but please do you have official method for reinstalling? I am going to use CentOS and want to migrate container itself to new host.

The [official install](https://meta.discourse.org/t/142537?silent=true) suggests ubuntu, I’m afraid you’re going to have to figure out how installation on CentOS will differ by yourself.
The scope of community support is limited, but if you have a budget you could also post over on the #Marketplace to have a consultant take a look.

Nevermind, if it is not Ubuntu issue but Snap, I will reinstall it. Thank you for your answer.

As I tryed several ways to make [official install](https://meta.discourse.org/t/142537?silent=true) - it was no success.
1. If I use [official install](https://meta.discourse.org/t/142537?silent=true) and trying to restore backup using Web interface or CLI, I allways have FAILED state.
Then I think that it is good idea to remove docker and reinstall it. So I purge everything related docker by command:
```plaintext
sudo apt-get purge -y docker-engine docker docker.io docker-ce
sudo apt-get autoremove -y --purge docker-engine docker docker.io docker-ce
```
After I trying
```plaintext
wget -qO- https://get.docker.com/ | sh
```
Everything is fine and
```plaintext
docker info
```
Shows no trace of snap. But as I trying to launch
```plaintext
./launcher rebuild app
```
I receive same error regarding read-only filesystem and
```plaintext
docker info
```
shows snap traces in path.
How to re-snap it?

That will not remove a docker installed with snap.
Run `snap list | grep docker` to find the snap package name, and the `sudo snap remove ...` to uninstall it.
