The discussion revolves around fixing broken images on a Discourse forum after upgrading to the current beta version. justin_gordon shares a post from the Meta Discourse forum suggesting three rake tasks to resolve the issue: rake posts:rebake, rake posts:missing_uploads, and rake uploads:recover_from_tombstone. However, codinghorror is skeptical about the effectiveness of these steps, citing their own experience with permanently broken images.
Benjamin_D points to a Meta Discourse topic that may help with finding missing images. gerhard suggests that the only way to recover the images might be through an old backup file.
stance455 tries the suggested methods but is still unable to recover the images. They share example posts with broken images and one old post where the images work, seeking further assistance.
Per this post
and suggestions on how to fix the issue, can anybody confirm that these are the right steps to take after upgrading to the current beta?
rake posts:rebake
rake posts:missing_uploads
rake uploads:recover_from_tombstone
Is there some good place that these rake tasks are documented?
I have broken images on this old post:
And I’m trying to set up my classic Kinesis keyboard. 
I’m on 2.7.0.beta1.
Thanks in advance for any advice, and thanks Discourse team for such a great product!
I’d say your case is close to the ones described here:
You are probably out of luck unless you still have a very old backup file that contains the missing files.
My apologies on resurrecting this one but after trying the above methods, I still can’t get the images back.
Perhaps a more experienced eye for these things will spot something
example post 1 and example post 2
However, here is an old one where the images work
