After upgrading from 8.12.1 to 8.12.2, only 4 of my agents are displaying upgrade available (non of them are fleet-server). Could this be due to the problem resolve of the other known issue or is this a new bug? I know I could try upgrading them via API or manually, but I wanted to make sure nothing else might be broken.

Is this a self-managed or a cloud cluster? Has Kibana been upgraded? Are the fleet-server instances running 8.12.2? ---

I am having [the same issue](https://discuss.elastic.co/t/agents-upgradeable-or-not/354354) in a self-managed cluster. Kibana has been updated, but I can't upgrade the fleet-server instances, because they are not shown as "Update available". All agents are installed from tarballs and were able to be upgraded before. ---

Is the Fleet Server on 8.12.2 as well? There is a [know issue](https://www.elastic.co/guide/en/fleet/current/release-notes-8.12.1.html#known-issue-3263-8121) about this. I had the same issue, I'm still on 8.12.1, but I've upgraded the Fleet Sever manually to 8.12.2 and it seems to have fixed this. ---

No. I wasn't able to upgrade the fleet-server because of that issue. I avoided doing it manually to be able to figure out the issue, but I guess if it's already known I'll just do that. That said - my agents are on 8.12.1, not 8.12.0? ---

> [@Balu](#): > > That said - my agents are on 8.12.1, not 8.12.0? The issue is still present on 8.12.1, it affects 8.12.0 and 8.12.1. The linked issue also has a workaround, did you check it? ---

Yes. I've tried the workaround, but the `curl` command is just returning an `Empty reply from server` and the agents still don't want to be updated. ---

I have now upgraded the fleet-server manually with ```auto /opt/Elastic/Agent/elastic-agent upgrade 8.12.2 ``` which took longer than what felt right, but it looks that now all other agents seem to want to be upgraded too. ---
