Help after updating from ssh site goes down

Product Support Self-hosting

AI-generated summary

After updating Discourse via SSH using the manual update guide kynic encountered a container startup failure with the error sethostname: invalid argument. tobiaseigen suggested running git pull followed by ./launcher rebuild app, but the same error persisted kynic. tobiaseigen then recommended running discourse doctor, which revealed hostname resolution issues — specifically, a long hostname causing problems kynic. Following this, kynic manually edited /etc/hostname and /etc/hosts to simplify the hostname to discourse-ubuntu, rebooted, and successfully rebuilt the app — resolving the issue. The site was restored, and kynic expressed gratitude for the assistance.

Try this instead:

cd /var/discourse
git pull
./launcher rebuild app

git pull
Already up to date.

./launcher rebuild app

I changed the hostname to ‘discourse-ubuntu’ earlier it was a long name, by editing these files…

nano /etc/hostname

discourse-ubuntu

nano etc/hosts

127.0.1.1 discourse-ubuntu
127.0.0.1 localhost

after that, I reboot and rebuild, and then it’s fixed finally. :grinning:

Thank you for all your help. :slight_smile:
