Not information on failed post-install while using install.yunohost.org

[Psycojoker]

I've been running curl install.yunohost.org | bash on a fresh stretch debian vps and answered yes to every question.

At the end, he asked me if I wanted to do the post-installation, I answer yes, he then told me that the post-installation failed whitout telling me WHY and asked me if I wanted to retry, same result.

We should display why the post-installation failed, it's not even written down in the log :|

End of the log of the post-installation:

The file /var/log/yunohost/yunohost-api.log is empty but /var/log/yunohost/yunohost-cli.log contains some useless stuff:

I've attached the SUPER LONG full installation log to this post : failed_installation_log.txt

We can't use curl install.yunohost.org | bash because of the way stdin isn't available or can't be propagated to the post-install command at the end of the script.

So currently that's the expected behavior, and the documentation says to use bash <(wget -q -O- https://install.yunohost.org/) ...

Either we are happy with this, or either we need to manage some magic to be able to have stdin available by the postinstall command. Or we can also decide to just tell the user to run yunohost tools postinstall (or go to the webadmin), which to me is no big deal and is a 10-seconds fix.

Indirectly fixed via YunoHost/install_script#54
