Are these accounts new?

If this is the case, what I believe is happening currently is that when you run this task, we would only delete accounts that are older than some amount of time. Looking at this particular task in the code, we would only delete inactive users that are older than 3 hours by default (this would be different if you explicity set ACTIVE_CODE_LIVE_MINUTES in your config).

Not all inactive accounts could be deleted automatically, there are more checks in DeleteInactiveUsers

I set ACTIVE_CODE_LIVE_MINUTES to 180 (was empty). Still nothing.

Inactive account from Dec 13, 2023 not deleted.
User doesn't have repos/orgs/packages
https://github.com/go-gitea/gitea/blob/main/services/user/user.go#L291C1-L291C6

The only thing I can think of is that I'm getting this green confirmation but the tasks is not executed.
How are those tasks executed?

I'm experiencing this problem as well with gitea 1.22.3. The newest account was made 7 days ago. Did you have any luck finding a workaround?

I don't remember it. Since I didn't close this issue I think I've removed them manually from database using the condition from the code.

I created #32318 to log the error reason.

Same problem here.
Task failed because it was trying to delete organization.
Response from log here is:
Task: Delete all unactivated accounts canceled: xyz is an organization not a user

[edit]
After moving organizations repositories to a user and deleted organizations, task deletes more users but not all. and no error nor log.
