When I run sudo apt update I see this: W: https://download.docker.com/linux/ubuntu/dists/noble/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details. As it’s only a warning I’m tempted to do nothing, but what do you a…

Hi, it appears to just mean that your gpg keys are not in the right place. apt-key(8) — apt — Debian testing — Debian Manpages *Recommended:* Instead of placing keys into the /etc/apt/trusted.gpg.d directory, you can place them anywhere on your filesystem by u…

[图片] itsbhanusharma: but the issue is not discourse specific In my case it arguably is Discourse specific (though not in the way you mean) as I only have the server for a Discourse installation that followed the standard installation instructions. But I’ll read the link you provided. Thank y…

[图片] Jonathan5: Though an idiot’s guide would be much appreciated. Take a full backup, set up a fresh instance of discourse and restore your backup there. That way you don’t need to mess with anything and in 99% of cases your issue will be gone.

I’d need an idiot’s guide for that too! For instance, I only learnt recently that a full backup includes not only the backup you get using the Discourse website but also the app.yml file.

[图片] Jonathan5: I’d need an idiot’s guide for that too! If you’re not familiar with a shell, I would recommend downloading the backup off your current site and following standard restore procedure . However, if you’re even a little comfortable in the shell or don’t want to deal with configuri…

[图片] darkpixlz: However, if you’re even a little comfortable in the shell or don’t want to deal with configuring a temporary site then I would recommend doing a CLI restore . This look simple, thanks. I’d be using a Digital Ocean droplet so imagine would have to update the DNS “A” record after…

[图片] Jonathan5: I’d be using a Digital Ocean droplet so imagine would have to update the DNS “A” record afterwards to the new IP address. Correct, if the machine has a new public IP you need to update the A record to point to the new server. [图片] Jonathan5: What about Amazon SES – I can’…

Thanks. I might do this soon then. I upgraded Ubuntu to 24.04 with Discourse in situ. It seemed to work all right, but this must just be an unforeseen consequence.

如果你不熟悉 shell，我建议你从你当前的站点下载备份并遵循标准的恢复过程。

但是，如果你对 shell 有一点了解，或者不想配置一个临时站点，我建议你从命令行进行恢复。
