Help! Upgraded server to Ubuntu 25.10 due to impending EOL for 25.04. Now when I attempt update Discourse it fails with this error consistently: [image] What is causing this?

Answering my own question. I proceeded to do a git pull and a launcher rebuild app and all is back to normal. I’ll leave the query here in case anybody else hits this issue.

[image] Andro: Upgraded server to Ubuntu 25.10 due to impending EOL for 25.04 It’s generally recommended to go with the LTS versions so you have to upgrade only once every 5 years. Though for many years I ran the latest available Ubuntu on my desktop/laptop, there’s not much advantage of living on the bleeding edge for a server.

I recommend moving to a new server when it’s time to upgrade as an in-place OS upgrade requires lots of downtime and might have issues. So I mostly don’t move folks to a new server until the 2nd LTS release (i.e., I’ve sites on 22.04 that I’ll upgrade this year, likely waiting until 26.04.1 gets released in the summer. Moving to a clean install requires zero downtime (especially if you can do it with a static ip that gets moved to the new server once it’s writing) working).

[image] pfaffman: an in-place OS upgrade requires lots of downtime I’ve done quite a few of them on ubuntu, and barely ever had a site out of comission for more that 2-3 minutes. Granted I’ve tested the process on staging to ensure there are no blockers but managing a fleet of two dozen or so servers justifies the extra steps.

That’s a good strategy but only works on systems that have that option, most of what I have is colocated hardware with no luxury of spinning up new machines at will.

I guess it’s been a decade or more since I’ve done one of those. I had no idea it was 2-3 minutes of downtime.

isn’t that a stretch? new lts is available every 2 years, but jumping 2 releases at once will be a lot to chew at once no?
