Hello, I am unable to upgrade/rebuild my web_only container. The rebuild seems to fail when calling multisite migrate. A fresh install (no data, just my data.yml and web_only.yml files) yields the same error (the rebuild of the data container completes without error. Am I doing anything wrong or could it be a bug introduced in a recent upgrade? Alternatively, how could I circumvent this error? I don’t know the internals of the script but the scripts first says that /root/ is unwriteable, creates a tmp folder then seems to crash because mkdir fails in the /root/ directory.

[תמונה] Padoup-Padoup: sudo -E -u discourse bundle exec rake multisite:migrate this should be sudo -H -E -u discourse… (we should probably make set_home the default)

It is unbelievable to me that I received the exact answer after… 25min :tada:! Many many thanks, the rebuild completed with success! Indeed, my web_only.yml contained the incorrect command. I remember following one of these tutorials: (that still contain the now-incorrect command ; not sure how to edit those posts). [תמונה] Guidance on multi-site setup Self-hosting Hi everyone! I’ve been working on setting up a multi-site Discourse instance, and while I’ve made some progress, I’m running into a few roadblocks and could really use some guidance from someone. I’ve gone through the Multisite configuration with Docker guide, but I still have a few questions: Where can I find the “multisite.yml” file that’s mentioned? I don’t see it in my discourse/templates folder. Do I need to set up hooks for after_postgres even if I’m just using the standard volume and n… [תמונה] Multisite configuration with Docker Self-Hosting warning While multisite is supported in the Discourse application, this is an advanced sysadmin setup. If you don’t know what you’re doing, do not set up multisite. The Discourse team is unable to provide multisite configuration support. If you wish to host multiple domains on a singled Docker setup, you’ll need a multisite configuration. Here are the basic building blocks for one. Understand hooks Multisite is a fairly advanced topic. Before attempting a multisite build, spend some time…

Yes it could, because I was in troubles when upgrade failed when wanting v10 and I had 9.something. So, I updated pnmp manually. And yes, I’m off topic because mine isn’t multisite and OP had different issue

@david / @cvx could this be related to pnpm upgrade we did recently?
