\nSSH into server,
\nrun dis-boot-res webxj to update Discourse
\nthen clear ssh log record
\nthen add Testing Boosts on Meta to plugins section of /var/discourse/containers/webxj.yml
\nthen run dis-boot-res webxj again and enable the new plugin.
\nAs the login banner indicates the packages of the Ubuntu 22.04 server are not up-to-date,
\nrun apt update && apt upgrade
\nbut it failed with connection too-slow and at-last timeout to archive.ubuntu.com's IPv6 address.
\nSo I substitute the URL archive.ubuntu.com with mirrors.ocf.berkeley.edu in /etc/apt/sources.list
\nAnd then update whole system packages again.

Side note:
\nThe performance of the VPS is too low. It takes too much time to dis-boot-res rebuild and restart the Discourse container. The disk I/O and CPU are too weak. The RAM is 4GB, somewhat disproportionate to 6 cores vCPU. May lead to slow loading.

Broken things:

Related topics recommendation relies on LLM embeddings. Check logs: /sidekiq/retries
Email login/registration. Fill in related settings in /var/discourse/containers/webxj.yml and rebuild container dis-boot-res webxj. See Troubleshoot email on a new Discourse install
