[SOLVED] Need some guidance with upgrading (lemmy.world)

Hi! I'm hoping for some guidance upgrading my instance. I'm still running on v0.17.3 because I ran into some issues upgrading to 0.18 and didn't have time to really figure it out. Now that the current release is v0.19, I have people on my instance asking to upgrade and I don't blame them. Can I simply point Docker compose at the latest release, or do I have to do incremental upgrades? What do I need to look out for with v0.18? Documentation seems to be pretty slim for whatever breaking changes happened during that release cycle and how to deal with them. Any help is appreciated!

EDIT: Thank you for all the help! I also had to update pictrs and fix some small config issues and then everything worked as expected. I'm now on 0.19.1!

I would move to 0.18 and then on to 0.19, how you get there will depend on how you setup in the first place. a look at your compose file would help

I created a gist with my compose file: https://gist.github.com/osiriswrecks/26a875576d3bbcf11923d7715ac15e6e. It should be stripped of all private info. I tried changing the version from 0.17.3 to 0.18.0 and the server returns a gateway error after restarting.

Update lines 33 and 48 with 0.18.5, then do a docker compose pull and then docker compose up -d

Once lemmy is up and happy, then repeat for 0.19.1

Upgraded to 0.18.5, which now gives me this error:

lemmy-lemmy-ui-1  | API error: FetchError: request to http://lemmy:8536/api/v3/site?auth=AUTH_KEY failed, reason: connect ECONNREFUSED IP_ADDRESS:8536

You might need to wait for lemmy to sort it's self out before lemmt-ui is happy

I can second this. It took a while after an update for the domain to show properly and not give an error. I don't know exactly how long but I started it in the early morning and it wasn't working but by 11 am it was all sorted out.

[–] penguin_ex_machina@lemmy.world 1 points 11 months ago (1 children)

Meaning I just wait a bit and retry later?

[–] mhzawadi@lemmy.horwood.cloud 2 points 11 months ago

Yes, I had the same issue when I updated to 0.19

UI doesn't come up until database migrations fully complete. Can take half an hour or more depending on how much content is indexed in your instance.
