Just found log after upgrading another production system to Bullseye. Seems to be related to boot files. As far as I can see, the UserClass was renamed to user_class is Transaction which is the only problem here.

So this is an issue in Debian's official 1.0.3-1 package in Bullseye as well? Or did you use dhcpy6d of git or upstream release tar balls?

Yes, sad to say but this error exists in 1.0.3 Debian package too:

This seems to look in the current 1.0.5-1 package from Debian Unstable/Testing. But, yes, 1.0.3-1 has that as well:
https://salsa.debian.org/search?utf8=%E2%9C%93&search=userclass&group_id=2&project_id=52793&scope=&search_code=true&snippets=false&repository_ref=debian%2F1.0.3-1&nav_source=navbar

So I should probably prepare a stable update in addition to preparing an upload of 1.0.7-1 — depending on the severity of this issue.

@HenriWahl: Can you give me a summary of the impact of this issue, i.e. what breakage can be caused by this, what feature doesn't work? I don't see such traces in my logs, at least not in those logs from this month.

Tracked in Debian as https://bugs.debian.org/995484

[HenriWahl]

@xtaran this bug leads to PXE boot malfunction. Not the main feature but unpleasant anyway.

Ah, thanks! I was already wondering what "boot" in the original bug report refers, too. Thanks for the clarification!

Works fine for me. Thanks.
