Hi!
I’m trying to import my old phpBB3 forum in discourse, by following this tutorial : [Migrate a phpBB3 forum to Discourse](https://meta.discourse.org/t/migrate-a-phpbb3-forum-to-discourse/30810)
But I can’t even prepare the docker container 😅
When I execute `launcher rebuild import` I have this error:
```plaintext
FAILED
--------------------
Pups::ExecError: apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y nano libmariadb-dev mariadb-server failed with return #
Location of failure: /usr/local/lib/ruby/gems/3.1.0/gems/pups-1.1.1/lib/pups/exec_command.rb:117:in `spawn'

bootstrap failed with exit code 100
```
It’s a brand new install of Discourse 3.1.0.beta2, on Ubuntu 22.04 LTS.
Any idea of what’s happening? Thanks for your help!

There is a bug that makes `apt-get update` fail. There is a workaround in this topic. You need to edit the template that you added (mysql, I guess) as a workaround.

I’m still looking at what’s up with that, but on an install I did 2 hours ago, I get this error if I do an apt-get update inside the container. root@monstera-web-only:/# apt-get update Get:1 http://deb.debian.org/debian bullseye InRelease [116 kB] Get:2 https://dl.yarnpkg.com/debian stable InRelease [17.1 kB] …
