submitted 1 week ago by [email protected] to c/[email protected]

What is Lemmy?

Lemmy is a self-hosted social link aggregation and discussion platform. It is completely free and open, and not controlled by any company. This means that there is no advertising, tracking, or secret algorithms. Content is organized into communities, so it is easy to subscribe to topics that you are interested in, and ignore others. Voting is used to bring the most interesting items to the top.

Upgrade instructions

There are no breaking changes with this release.

Follow the upgrade instructions for ansible or docker.

If you need help with the upgrade, you can ask in our support forum or on the Matrix Chat.

Thanks to everyone

We'd like to thank our many contributors and users of Lemmy for coding, translating, testing, and helping find and fix bugs. We're glad many people find it useful and enjoyable enough to contribute.

Support development

We (@dessalines and @nutomic) have been working full-time on Lemmy for over five years. This is largely thanks to support from NLnet foundation, as well as donations from individual users.

If you like using Lemmy, and want to make sure that we will always be available to work full time building it, consider donating to support its development. A recurring donation is the best way to ensure that open-source software like Lemmy can stay independent and alive, and helps us grow our little developer co-op to support more full-time developers.

You'd need to post your dockerfile, that's not an official install method so I have no idea what's wrong.

[-] [email protected] 1 points 1 week ago

I'm using the regular Docker file, and I'm getting the same thing.

Lots of the following in the UI logs.

{ name: 'couldnt_find_person', message: '' }
{ name: 'couldnt_find_post', message: '' }
{
  name: 'unknown',
  message: 'Query deserialize error: invalid digit found in string'
}
{
  name: 'unknown',
  message: 'Query deserialize error: invalid digit found in string'
}
{ name: 'couldnt_find_post', message: '' }
{ name: 'couldnt_find_post', message: '' }

However, Photon's alternative UI works fine.

I can't tell which version of lemmy-ui you're running, or the env vars without your dockerfile.

Env vars are here: https://github.com/LemmyNet/lemmy-ansible/blob/main/examples/vars.yml#L43

Below is my current dockerfile, which is using 0.19.11 right now to fix the issue. The issue happens when I switch to 0.19.12.

The lemmy-ui env vars look wrong to me.

Right you are, I messed up the external host. Thanks!
