I’ve set up a Lemmy instance and tested federation by commenting with my Mastodon account on the lemmy instance, which worked.
But I broke the test instance and had to start over (not even once).
The productive instance runs now, but after a few days I figured out that there is still the old post from the old installation on Mastodon and over Mastodon I can’t see the new post and no new comments?
It is the same link (older Mastodon post, old Mastodon post, new Lemmy post), but the content is different.
- The post itself doesn’t update (it is completely different)
- The comments don’t update (different comments)
How to solve this problem? Is it even solvable?
I tried to copy some posts, but it looks like it is totally screwed up, now. Even higher ids show wrong content on some Mastodon instances, even if I am sure I only did a few tests with posts.
Only way to solve this (imho) is to reinstall Lemmy BUT use another subdomain.
What do you think? Will this work?
I wold agree that this is worth considering as an approach to not clash identity and get into custom SQL or Rust programming. But there isn’t even really a procedure in place to decommission the old lemmy entity… so another damned if you do, damned if you don’t in 0.18.4 era.
I’m a little surprised that the federation private key/public key signing doesn’t get upset about all new keys appearing on the same domain name. I’ve tried to get details of exactly how a server joins the Lemmy network and gets discovered over on !lemmyfederation@lemmy.ml but haven’t gotten any actually discussion on the details.
I’ve seen people nuke and start-over their database from empty several times while having problems setting up NGinx and Docker… or whatever part.
I’m glancing at the list of SEQUENCE in Lemmy…
