We’ve upgraded lemmy.world to 0.18.1-rc.1 and rolled back that upgrade because of issues.
(If you had posted anything in those 10 minutes between upgrade and rollback, that post is gone. Sorry!)
The main issue we saw is that users can’t login anymore. Existing sessions still worked, but new logins failed (from macos, ios and android. From linux and windows it worked)
Also new account creation didn’t work.
I’ll create an issue for the devs and retry once it’s fixed.
Edit Contacted the devs, they tell me to try again with lemmy-ui at version 0.18.0. Will try again, brace for some downtime!
Edit 2 So we upgraded again, and it seemed to work nicely! But then it slowed down so much it was unuseable. There were many locks in the database. People reported many JSON errors. Sorry, we won’t be on 0.18.1 any time soon I’m afraid…
Thank you for the transparancy!
I love post like this, another reason of why this instance is so good
Thanks for all your hard work @[email protected]. It’s not easy!
As any engineer who does ops can tell you - you did the right thing - the solution is always to roll back, never force a roll forward, ever.
We should totally do pre and post update parties though. Even if the update fails we can have an excuse for drinks and a fun thread.
Although since we seem to be rolling more than a ship in a storm, I think a proportion of lemmings would end up hospitalised for alcohol poisoning.
UI: 0.18.0 BE: 0.18.1-rc.1 👍
seems to be working for me, I was already logged on
is that users can’t login anymore
Ouch, that’s bad :(
Thank you for your work, as always :)
I mean that’s a Tuesday on Reddit lmao.

We have one! This was tested on a test instance before
Cool, great minds think alike 😁
Yeah we have a test instance, but not sure if we could test with this kind of load…
Thanks for the hard work /u/ruud, we’ll get there
Both Dessalines and Nutomic have been working their butts off to get 0.18.x ready for the Reddit API changes. Huge hopes they can pull through!
Dessalines:
Nutomic:
Yeah they’ve been hard at work all month. But it’s also okay if things aren’t ready in time. Most of the people who matter are already here.
Maybe we will blow up soon, maybe later, but the quality of content here is sufficient to drive growth regardless of whether or not we get the prophesized huge migrations from reddit
Agreed. I’m here to stay with the content from the last couple weeks. 3 day poop embargoes alone is worth it. And recognizing users because the community is still small enough is SO different from they who shall not be named.
Oh god, so much coffee… it’s also thrilling to grasp a sense of what’s going on under the hood of such big social networks at a development level (not like I could understand it, but it was very interesting to see twitter’s recommendation algorithm being open-sourced)
Just curious, why are we updating now instead of waiting for the proper 0.18.1 release?
Because of a few things, really anoying bugs and the Jerboa app not working properly with older versions
I suspect there will be a large influx of new users in two days, and that having Jerboa not working on .world might cause a few issues
For example the frontpage is no longer being constantly filled with random posts when you set the filter to “active” or “top day”.
Reasons I can think of:
-
The official Android client for lemmy, Jerboa, only supports 0.18 and later, unless users download older version from github and sideload manually.
-
Sorting is broken pre 0.18, new posts keeps flowing in.
-
Performance improvement by removing web socket from lemmy. (which fixes 2, which is why 1. happens)
Try wefwef.app on mobile
(no I’m not a bot account shilling I just really like the app)
If there was a way to adjust the font sizes it would be 100% perfect. Damn! I’m surprised I hadn’t heard of it before. Thanks internet stranger!
Nice and thanks!
Question: Where’s the edit button? I can’t find it.
It’s an open issue on their github (https://github.com/aeharding/wefwef). Will probably be available soon, the development seems to be fast - I got two updates in a single day. Also tagging @[email protected]
Oye spaceduck, tas rechulo y lo sabes. !tip 12
Why the hell does Jerboa even limit support to 0.18? That’s so stupid.
Connect for Lemmy works better.
Is it open source?
The latest version only supports 0.18 because the backend works differently. Older versions of Jerboa support older backends of lemmy.
Likely because Jebora is written as a side project of the devs of lemmy so it’s always going to be cutting edge
I understand that. I’m not complaining about the quality. I’m just confused from a technical perspective why it doesn’t support rollback or older server versions in the event of…this.
Fixing the issues with posts appearing and scrolling the page the backend needed some pretty drastic rewrites. I’m not super familiar, but from what I’ve seen of the code, it would be a decent amount more work to support both versions.
Would it have been worth it? Yes, but it wasn’t anticipated that devs would stay on 0.0.17 for more than a day or two. With the time it takes for app stores to update, servers would have been updated before lemmy 0.0.45 was updated for the vast majority of users. At most, it would be a day or two instead of a week or two.
Jerboa works fine with lemmy world, it just gives a warning and crashes on occasion. Not an issue to use it though.
The latest update of jerboa did not let me browse all communities. I had to sideload a previous version.
Yes, if you are already logged in. If you are not logged in, or get logged out you will not be able to log back in until the server version is above 0.18
For me at least, I’m unable to change the community scope or sorting method. The only thing I can use Jerboa for is “local” and sorted by “active”. It isn’t totally unusable, but I would much rather be able to switch to subscribed and hot.
I had the same bug. A full restart of my phone seems to have fixed it.
Unfortunately that didn’t work for me. Thanks for the idea, though. I’m sure it will work for some. I suspect that if I wiped the app and set everything back up it might work, but that’s more than I’m willing to do at the moment and I can live with the inconvenience for now.

That sounds like Bethesda’s definition of “works fine”
That is absolutely not “fine”.
“crashes on occasion”
Unfortunately, the occasion seems to be at least once every five minutes for me. thisisfine.jpg This is not fine and definitely a major issue. Especially as we get closer to July 1. After this news from lemmy.world, I will have to switch, until Sync arrives. Update: Liftoff is fantastic, give it a try!
Have you tried this fork? https://lemmy.ca/post/899342
As a new user I tried logging in on Jerboa and it says the server must be on 0.18 and refuses the login.
Have you tried this fork? https://lemmy.ca/post/899342
Thanks for the link. I knew could side load an older version, I just wanted to be lazy and use something on the play store. I’m trying out several clients right anyway.
It won’t let me log in, so no, it doesn’t “work fine.” But I have six other apps for Lemmy, so I’m not worried. It’ll all be sorted eventually.

The official Android client for lemmy, Jerboa, only supports 0.18 and later, unless users download older version from github and sideload manually.
Even that won’t work, because Jerboa initially tries to connect to lemmy.ml which is running 0.18, which older versions of Jerboa aren’t compatible with. The app just crashes instantly without giving you the opportunity to log in to your instance.

Federation is completely borked with .18 servers. Its very difficult for us to interact with https://lemmy.ca in any way: subscribing, upvoting, comments, posting… its all bugged.
Its maybe not that big a deal because Lemmy.world “has the most users”, so in some regards its https://lemmy.ca’s loss but… we need to restore reliable federation… especially before the July 1st rush IMO.
The .17 to .18 upgrade is basically a soft-defederation event, because of whatever this bug is between the two versions.
Ah that explains it. Someone posted a cool photo to my community from lemmy.ca but didn’t interact further. Looks like my comment didn’t even show up on their end.
Anyway, thanks to everyone working on the issue. I know these things aren’t easy.
I’m subscribed to lemmy.ca and programming.dev, both of which are .18 now. Feels kinda bad losing access to those communities while this issue is getting worked out…

UI at 0.18.0 and backend at .1rc1
Yep we tried bringing both the UI and the backend to 0.18.1-rc1 but that gave issues. Lemmy devs told us to try this combination and that seems to work. 🤞
Just curious, why are we updating now instead of waiting for the proper 0.18.1 release?
A Release Candidate is supposed to be past beta testing already and in a state of no major bugs.
@[email protected] just wondering if you have considered setting up a second, beta, instance of lemmy.world open to the public?
With all the performance issues with 0.18.1, it’s highlighted that there needs to be a way to stress test these updates before applying them to the main instance.
Yes, considering that. But we’ll need people to use that when we will do testing…
I’m not familiar with what the server architecture looks like, but is there a possibility of using a load balancer in front of the instance’s server and swapping a “beta” server into the load balancer when you need to do testing? You could basically migrate your traffic with zero downtime, assuming Lemmy’s architecture allows for it.
Well that doesn’t differ much from what I do. I just copy the files to a second directory and test with that. Easy rollback. Downside is, that all data is lost between upgrade and rollback, which will be the same in the scenario you suggest.
Ah, that’s fair. Best of luck either way. This is the tough part of admin work. FWIW, the stability we’ve had thus far has been pretty impressive!
Well, you have at least one person who would be willing to use it ;D
One more. You find a stable way to notify anout upgrades and get a test sheet to run through and we can generate posts and activity to help test with.
Light the beacons! lemmy.world calls for aid!
Is there a way to have two instances writing to the same db? That’d help a lot in this situation so the test instance can still be accessing the same data as the stable instance. Otherwise we’ll never have enough load to fully stress test and be in the same situation as the three existing Lemmy test instances.
Seeing that with these updates often come with changes to the database as well, that could be very difficult if not impossible.
Eveyrthing (UI) is extremely slow now. Not an improvement at all.
Same here. Almost unuseable
Same here. Almost unuseable
Same here. Almost unuseable
I’m experiencing the same too.

Thanks for the transparency. Maybe it’s a good idea to have a test instance and some test cases/validation done there before updating the main instance. This is a regular process in any software/tech company/stack.
Testing should never be done directly on the prod instance.
i think they tested it which worked fine, but it is totally different when there are users online
Correct there was a test instance and that worked fine but once the live instance was upgraded everything became very slow. Can’t really emulate that kind of load
Jerboa crashes constantly for me now, doesn’t even let me view anything. JSYK!
You might want to try https://wefwef.app
There’s a fix the dev has just released. See reviews section on the app. He said it’ll take a few hours to show in the playstore.
This is good news! I haven’t been able to try Jerboa fully yet since I use lemmy.world. I’m not seeing this review section you’re talking about but I’ll be on the lookout for an update. Thanks for sharing!
Sorry, my comment wasn’t very clear. On the app page within the playstore, if you scroll to the bottom and read the reviews you’ll see the developer has replied to say a fix will be released today. I’m yet to see it though.
appreciate the transparency. how are things looking in the back in lemmy.world (server wise)? will we get to a point where it wont require complete rollbacks on the state when a botched update gets rolled out?
My current session works now with 0.18.0 + 0.18.1.rc1
