Hi, I read this post: PostgreSQL 15 update - and tried to upgrade to version 15, however when running the rebuild command, I’m running into errors that I’m unfamiliar with, and non of my research has solved the issue. I would appreciate any help I can get here. It complains about both Locale and po…

Thanks for taking the time. I completely missed that memory thing, here’s the results you asked for: root@glorious-discourse-forum:~# cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=18.04 DISTRIB_CODENAME=bionic DISTRIB_DESCRIPTION="Ubuntu 18.04.5 LTS" root@glorious-discourse-forum:~# uptime…

Thanks. I think you could try just adding 2G or 4G of swap. But the message about out of date Docker, and the running of 18.04LTS, means you’d be in a much better position if you migrate to a new instance with a fresh new OS installation: 24.04 preferably. I run both 24.04 and 22.04 at present. M…

Oh, another approach to migration, instead of backup and restore, is to use rsync. I haven’t done it, but here’s a recipe: Move a Discourse site to another VPS with rsync

The other issue is your Docker version and OS need upgrading. [圖片] glorioustn: WARNING: Docker version 20.10.7 deprecated, recommend upgrade to 24.0.7 or newer The Docker version 24.0.7 or newer requires a higher Ubuntu LTS than 18. The long term service on that LTS is out support.

So I ran into this same exact error except I ran ./launcher rebuild, I hadn’t been following the forums and warnings and kinda just blindly ran the update. How do I kill/revert this run? Just Ctrl+C out of the run?

What happened? Was there an error? Did it say to run the rebuild again? Did you upgrade docker? Did you try ./launcher start app Did you look at PostgreSQL 15 update

it stopped doing anything after DETAIL: The data directory was initialized by PostgreSQL version 13, which is not compatible with this version 15.10 (Debian 15.10-1.pgdg120+1). I power cycled the server and that brought the server back. Running some more updates now with Docker being stuck on 20 …

Bummer. I would wait until Monday and move to a new vm. I’m guessing this one is beyond end of life

这可能是最严重的问题——您需要更多的内存（RAM）或需要添加交换空间（swap）。
